Why the fuck are you looking like Alice Cooper?...

I had a weird dream! The kind of dream that you keep in mind for a while after you woke up.
I don't know if I was in the future or on another planet, or in a parallel dimension or whatever... but it was kind of "futuristic". It was kind of awesome and freaking at the same time...
At the beginning, I was on what looked like a coach. But I was sitting upstairs, as if I was on a double decker bus. It looked 'normal'. Then I started to stand up because I was getting off. I had 2 bagpacks with me (1red and 1black) and I also was carrying a black hoody jacket. As the coach was moving, I got down the stairs carefully.
There, the coach didn't look like it was upstairs, it was bigger, I mean larger. It was a huge shuttle, a long and very large carriage.
As I walked to the door, it was like walking on a spaceship... and everything was black inside (Big black sits, black carriage's floor and structure, and no windows) so it was quite dark, a bit like when you walk through a dark cinema's room.
And the sits were kind of big armchairs, kind of like that famous Herman Miller's leather armchair, if you see how it looks like. And there were also big tables near by the door. An automatic door. With the 'tch' noise, exactly like in sci-fi movies. It was open but before I could get off it closed down, so I had to wait for the next stop.
As I had to wait, I sat down at one of the table (a table for 6). I put my 2bags and jacket in front of me, on the table.
But at the next stop, I didn't have more chance to get off because the doors staid open for a fractionnal time only.
So I thought I'd better get myself ready for next opening, standing and waiting just near by the door.
Then when the door opened again, I managed to get off, hurrey! But once on the platform, I realised my 2 bags and jacket were still on the table. So I ran back on the coach and grabed my bags superquickely and I jumped off again.
I did it!! But again I realised I had left my jacket behind. I thought it didn't matter, I wouldn't have time to pick it up before the door close anyway, so I decided not to play this game again.
Then the coach moved away... I was at a 'bus-stop', wich looked like a big open-air platform. And it was raining a lot. Well, not really raining, cause soon I realised it was in fact some water spay on the stuctur of the platform. And sounds of rain were coming through a speaker.
And it was hot. I understood they had to fake the rain because it wasn't raining anymore in this 'world'.
I started runing to not get wet. I was running in the street going fuck knows where and I started to hear the voice of my friend in my mind. It was a memory, I was remembering him telling me the direction to go to his house.

So I understood I was in the future and I was going to a place that used to be familiar to me. I was in the future going back to a place familiar to me in the present.
(Well, that's the feeling I had, it's not very clear because apparently I didn't go there for years because my friend's voice telling me the way to go there really sounded like an old memory. And another anachronism is the fact I wasn't looking older in my dream, I was just myself as I am now.)
So hearing the memory of his indications, I kept on going. I was still running (I don't know why?), maybe I was in a hurry to find him. Yeah, I think I was looking for him for some reason..., and I arrived behind a guy on a white bicycle.
I was running behind this guy on a white bicycle and he was wearing a black hat. Then looking at his back and at his neck, I had the feeling this guy could be my friend older. If I was in the future, it made sens my friend would be older... So I called his name. He almost fell down. He got on the side of the street where he stopped and looked at me. This guy looked like Alice Cooper (don't ask me why, there are no connexion between Alice Cooper and my friend, except they're both musicians. And I've never had any interest for Alice Cooper. I only know his name is Alice Cooper cause I've watched Wayne's World so many time when I was teenager). So to come back to the end of my dream; the guy who looked like Alice Cooper, looked at me. He seemed kind of shocked and he said my name (and something else that I can't remember... was something like: "you're coming back with your same young voice"), so I understood I had seen right, this guy was my friend but older and looking like Alice Cooper... uh?
So I had a feeling of great happiness and relief of finally having found him and being reunited, but he didn't seem as happy to see me, as I was to see him.
I'd even say he looked kind of 'angry', but I don't know why, cause then I woke up.
Was he just a bit bitter cause I was young and he wasn't?...
Or is it more complexe?... I'll never know...

Why did I wake up before having more details... I wanna know why he didn't seem happy to see me! And also, why the fuck he was looking like Alice Cooper?...

Now what song is in my mind... to be honest, I don't have any songs in mind right now! I'm still too disturbed because of this dream... So let's simply do a "dreams" thema list:
