A dream begging to be interpreted

.*
There's a secret room at my apartment. My dad gave it to me and I needed to protect it. I can travel back in time in the room and there is something valuable there (not sure) there is a specific key to get inside. I show my friend but he tries to steal the room from me and keep all the valuable things there to himself. He surprises me and shoots me three times in the chest but I remember putting a bulletproof jacket on earlier.*
This friend is now and enemy and my house is more like a Hotel.
It has a specific reception area and some high-tech security. I think someone tries to steal from me again but I catch him.*

Now I'm*
Running into a crowded place. I'm not sure why but I know there's a tower (like repunzles) I'm running away from and im also trying to look For someone *There's a traffic jam so I run on top of trucks and cars. People in charge of a local non profit organization ( which i used to be part of) are looking for me but I avoid them. *I'm running away from them too and I get on top of a truck and hold on really tight.*

The truck drives to my house hotel and stops, this is when I confront the president if the charity organization. *He asks why I haven't been participating and that they want me back. *I say that I lost a lot of my friends because the decisions I made and that prevents me from coming back. He understands my half truth half lie and leaves.*
*I'm at the reception to my home, there is an explosion. Everybody survives but is cut in half and is mostly shocked and just standing there. I remember this one teenager who just licks his hand wound and seems indifferent. * I notice one guy trying to leave he seems took nonchalant and so I grab him in a chokehold. He is stopped *I notice he was trying to steal from me again. I find a locked briefcase that I assume has my valuable things in it and calm down.*

Near the end of my dream I find myself in my secret room which now looks like a bathroom with stalls. Everything is made of concrete. I start putting costumes of superheroes on but in a mosaic way. The head is batman, chest piece is spiderman and the legs are super man (not sure about the legs)I look out my window and see a peaceful view of night slighly obstructed by the batman headpiece. I go pee. (I went *earlier in the dream and both times there wasn't at a toilet, it waS just a stall with a floor) while I'm peeing I feel a pain and decide it's a renal stone and just use more pressure. I wake up to a bit of urine in my bed. I'm completely shocked I wet the bed.

*I'm a 22 year old 2nd year med student. I've wet the bed last year and that was really embarrassing because my girlfriend was sleeping next to me (didn't dump me haha). I cant remember the dream I had that time but I remember I was trying to urinate into a toilet and woke up.*
More info on me.. Um Ive done 4 years of college and I have a girlfriend. Because of that girlfriend I lost many friends but that was a decision I made consciously because she helps me get thru school and they don't. I'm also really stressed out right now because I'm preparing for the board exams.

I have my own analysis of this dream *but I wanna hear what you guys want to say about it. *A lot of things are going on so if you want to pick up one part and talk about that you're more than welcome. The wetting bed part is what made me write all this stuff down but I think there are some bigger issues here. *Thanks in advanced.
