Lucid Dream - I think I know this person???

Last night I had a very lucid dream, it has shaken me so much I cannot stop thinking about it, and I am hoping someone here might kindly offer some explanation or interpreatation.
For a bit of background info, I am not a regular lucid dreamer, I can probably count on two hands the number I have had in my adult life, but this one has really got to me.

Basically, in my dream there was a man. In my dream I was aware he was from my past, I knew him very well, he was deeply familiar to me. He was a very good friend and in my dream it was the first time I realised how much I LOVED him, like romantically, and I was completely in awe that this man had been there all along and I hadn't realised quite how amazing he is. There was a point in the dream where we watched an old video tape of he and I laughing and stuff, and I was thinking, wow, he is so amazing and nice and I can't believe he is here now. He was just lovely, calm, warm, caring, I felt very safe and at ease with him, I felt whole. Even whilst I was dreaming I was aware it was a dream and I was trying to figure out how I knew him and where I would be able to find him when I woke up. Nothing romantic or sexual happenned in the dream, at one point I hugged him and the feel of his arms around me felt so incredible that despite waking up there is still a trace of that amazing feeling.

As I explained, he was deeply familiar to me, I have never felt to comfortable and happy to be with someone in all my life. Anyway, upon waking, I don't know who this man is. I don't think I have ever met him before and I actually feel sad about this! I mean really sad and just pissed off about the whole thing. A dream has never affected me this way before, it is so strange.

What was this? What does it mean? I feel a bit stupid saying this, but I want to find this person!

I just want to add, that the sadness I feel, it is a bit like the realisation that someone has died. I know that sounds dramatic, but its the only thing I can relate it to, like hes gone, and I miss him horribley. Its not nice.

He hasn't gone anywhere? if you really want to meet him again, make an intention to meet him before you go to sleep.
Don't let yourself get too attached though, it is just a dream.

I meet amazing girls all the time, but hey you have to let them go somtime.

I think I know what you are talking about. Sometimes you get dream characters that don't exist in real life, but they are consistent in your dreams as if they are real, which is unusual. Especially if you feel emotional attachment to them. It's almost a dream sign?

I used to have a 'friend' in my dreams some time in the past. She appeared in numerous dreams. Detailed and consistent character. But all dream characters are all nothing but your yourself.

Believe it or not, your mind cannot create a person entirely unique -- their features are always going to be based off of someone else.

One day I'm sure you'll find a man just like that in the waking world. =) Let him be an example of what you seek.

It is sad that this man does not really exist, but maybe you could use him as an example of what you are looking for. Try to identify the qualities in him that brought you this feeling of love and comfort. Seek out those same qualities in the people you meet in real life.

Taking it one step further, and try to seek those qualities in yourself. Treat others the way he treated you, and you will be honoring his memory. You will be bringing his spirit into the real world through your actions.

It could be a dream guide. Just a thought as it fits the description.

Usually people describe their DG as perfect.
