I remember few, but those that I do remember, stand out in how bizarre they are to me. I only remember a few details about them, so they're pretty short:
1) I had this one when I was quite young. The entire world was purple and black, and some people who were in a different class than me (but still my level) rode around on some giant chrome-panthers, permanently outstreched with their front paws forward and hind legs backward, just like the panther that Jaguar uses for a logo. I recall it as an unpleasant dream, these were not the people I wanted to see.
2) From what I remember, it was a western-themed dream, but I think it played out in the area where I went to school. Anyway, the only thing I do remember about the dream is I shot a guy, and his head just fell off. Not in a bloody mess or anything, I just shot him in the chest or something, and his head fell off as if it were an ornament placed precariously on a table.
3) I was driving my father's car around for some reason, and for some reason this girl from (what equals to) junior high was there, and for some reason I was driving the car underwater, looking for a way up.
4) Probably one of the freakiest dreams I've ever had, I remember hardly anything from it, except the part that woke me up. A giant looming shadow over me with a menacing laughter that echoed in my head even as I woke up. I can't describe it, but it was the absolutely most sinister and scary laughter I have ever heard. Definitely a nightmare, I think all of it was kinda fucked up.
