Can't decipher a weird dream. Need help.

Hello.

I've had this dream about 2-3 weeks ago, and ever since I've been trying to give it some meaning, or to decipher the lesson behind it but I cannot. So I came here.. hope you can help.
Nothing special happened in my life that could've triggered this dream. It was a normal day.

It start with me in a formal attire, close-up on my face. To note that I am uncomfortable wearing a suit and I hate close-ups on y face. The view pans back revealing that I am in a group of people that appear to be my friends, mostly because we're all standing in a circle, talking, but I don't know them in real life. But something was on my mind. I felt detached, preoccupied. Then the surroundings were revealed. It was a combination of an opera hall, with red velvet carpet and drapes ( yes, they matched ), beautifully sculpted wood elements, a bar, a stage as if it was set for a techno party ( I dislike techno ) and an indoor amusement park with kind of a wonky tilted ferris wheel in which you laid on your back like in a coffin, face towards the ceiling.

I sit there, in that group and wait. I feel frustrated and keep looking at my watch. I'm waiting for my girlfriend. I cannot hear the music, the other guys, nothing. It's total silence. Then someone catches my eye. A woman. Tall, long black hair, light blue eyes ( Olivia Wilde like ), dressed in a bright red dress, like molded to fit her body only. Her hair was down to the middle of her back. She also had a tongue pierce. She looks at me. I look back. She smiles, bites her lip then continues on walking towards a seat. I feel ashamed. Like I cheated on my girlfriend with her. I go to the bar to order tequila. I down 5 shots. ( Tequila is my favourite drink ) I sit there. I talk to the bartender, but I can only hear the music. It's Bad to the Bone by ZZ Top. ( The favourite song of a woman I once loved ) It feels like I've known him forever, like he knows my story. I can't see him, only his left arm. It has a tribal tattoo. ( My cousin has a similar one. We are more like brothers than cousins ) The I go to the seat where that woman is. Still anxious and detached, but now I feel mad. I sit next to her and say:
"What are you doing here?"
"You wanted me here."
"Why would I want you here after all that happened?"
"I don't know why. I just know you do."
(Even weirder, I'm not a native english speaker. My first language is romanian, second is hungarian, 3rd is english, but everything I hear is in english )
I stand up, and walk away.

Next "scene" I'm on the ferris wheel. It shows me trying to relax in the coffin type "seat". I almost crash into object that appear out of nowhere, but avoid them. I see my girlfriend. I know it's her because I can feel it, somehow. But it's not my real life girlfriend. IRL she has long red hair, small lips, puffy, as I like to call it, body (as in she is not totally fit, a bit curved ) and she has green/brown eyes. (green on the exterior, brown on the interior). My dream girlfriend is fit, blonde hair down to her shoulders, red luscious lips and eyes of the deepest blue I have ever seen. Kind of looks like Madilyn Bailey. I feel betrayed. As if I now know that she has been here all along and didn't tell me so I can spend time with her.

I get off the ferris wheel and go out for a smoke. I'm smoking Marlboro. I usually smoke Lucky Strike, and Marlboro make me sick to my stomach. It's a dark alley, lighted only where I walk. It's like the light follows me. Out of nowhere, a guy shows up to hand me a light. He's wearing a brown trench coat and a brown hat, mafia style. His lighter was a golden Zippo lighter with a red flame. I smoke half of my cigarette, and out of the darkness, a bunch of people come out, surrounding me. I can distinguish a doctor, a plumber and a soldier. The doctor tells me I have cancer. I wake up.

Thank you for taking your time to read this.
Sweet dreams.

The silence, the feeling of being isolated. Maybe on a social level in real-life ? Do you have many friends on your level/close friends ?
The women, the bartender and your girlfriend. Betrayal (the feeling). Relationship working well ? Does your surrounding accept/know about your lucid dreams ?
The soldier, the doctor, cigarettes and cancer. Do you live unhealthy and fear illness/death ?

Seems to me as if deep down inside you there is a longing for something better and more meaningful on a certain level. Which one i do not know, but i gave you some thought-food above.

Never forget that your dreams speak to you in a language for you alone to understand. Others can only guess, the truth in them speaks to you if you start to listen.

So far, sweet dreams

Thank you Lucyfer. :)

Let's go over this piece by piece.

When you wear formal attire in dreams it means that you want to be recognized and acknowledged for your abilities and skills. You don't want to go unnoticed. An opera house usually represents your quest for the grander things in life. The dream may also be trying to tell you that you are being overly dramatic in some waking situation. To dream that you are at a bar suggests your desire to escape from the stresses of your daily life and retreat into a light-hearted environment where pleasure abounds. You could be seeking acceptance in some aspect of your daily life. The dream may also be a pun on being "barred" from some place or something. You are feeling excluded or held back by circumstances beyond your control.
To see or be in an amusement park indicates that you need to set some time for more relaxation and enjoyment in your life. The rides, booths and elements in the amusement park are an expression of some aspect of yourself or some area in your life. A Ferris wheel specifically suggests that you are going around in circles. You are headed nowhere. Life is full of ups and downs. Having coffins for seats could mean that you are going through a period of depression. You are feeling confined, restricted and lacking personal freedom. There may be a dead or decaying situation or issue in your life that you need to address. It is time to end this situation.
The woman could be a physical representation of your inner temptation and guilt. The red color of her dress matches this as the color red means intense passion, aggression, power, courage, impulsiveness, shame, rejection, sexual impulses and urges. The color red has deep spiritual and emotional connotations. Consider your conversation with her being you talking directly to some or all of these inner desires.
To see your girlfriend represents your waking feelings and relationship with her. Her altered appearance represents things. Blonde hair means that you need to enjoy your life with her and live it up more often. If you notice someone else's eyes in your dream, then it indicates an emotional or intimate connection with that person. It also signifies a mutual understanding. Seeing as how she's your girlfriend, this makes sense. The color blue in her eyes standing out to you means something. Blue represents truth, wisdom, heaven, eternity, devotion, tranquility, loyalty and openness. The presence of this color in your dream may symbolize your optimism of the future. You have clarity of mind with her. Alternatively, the color blue may also be a metaphor for "being blue" and feeling sad when it comes to her. To dream that something or someone is thinner represents a lacking of strength and integrity. You feel that you are unable to hold your own or stand up for yourself. However, this also indicates flexibility and agility. You are able to adapt to any situation with her. Lips in dreams signify sensuality, sex, love, and romance, especially if they were pursed. Their color being red enhances this, and shows just how deeply you feel these things about her. Betrayal being such an impacting feeling when seeing her shows your suspicions about a particular person, relationship or situation. This feeling often occurs when you are having feelings of insecurity and are faced with major commitments in your life at the same time.
To dream that you are smoking signifies your need for a break from things. It may also point to issues of dependency. You smoke directly after seeing your girlfriend. You are typically against smoking that kind of cigarette, showing that you need to analyze aspects of your waking life and what you are doing that may adversely be affecting you.
To dream of coming in contact with a mafia person is a representation of your inner turmoil, much like the female was a representation. Your turmoil is lighting your cigarette, this may show that it's your inner turmoil that may be what you need to analyze in your life. The color gold means many things, but the negative aspects seem to be what it represents this time, those aspects being, greed, corruption, and temptation. Your inner turmoil is causing these things in you.
Doctors represent a need for emotional and spiritual healing, a plumber represents that there is some emotional issue that you need to deal with instead of letting it clog up within you, and a soldier means that you are preparing yourself to do battle over an issue. You feel the need to defend your beliefs, values and opinions. These feelings are telling you that you have cancer. Cancer in a dream represents the areas in your life which are bothering you, disturbing you, and hurting you in some emotional way. An emotional issue is eating away at you. Them telling you this shows that your subconscious wants and is preparing you to deal with any issue you are having, and not to hold on to these issues.

I got these meanings from real dream interpreting guides. All these different symbols meanings match up quite perfectly. I hope this has helped you.

Thank you both very much. I'm now know pretty well what the dream was telling me know.
Again, thank you.

Pleasant dreams. :)
