I love dreams, truly love them. Sometimes my brain really goes to town and conjures up an epic action movie for me with a plot that actually makes sense (sort of). I have various "sets" that recur in my dreams, one of them being a skyscraper or tall apartment building that's like a hi-rise city with all sorts of stuff going on. One time I dreamed I lived in a hi-rise, but instead of having an elevator, the entire building raised and lowered itself to let people out at street level. You were sitting there in your apartment going up and down all day.
I can still remember dreams from when I was a small child. I bet everyone has a few childhood dreams that really stood out and they never forgot them. In one, I was trying to get up some stairs in a tenement building to visit my grandma, but the entire building started filling up with soapy water and eventually turned into a washing machine on a full spin cycle. In another, I was strapped to a floating gurney and was hovering down a dimly lit hallway in what looked like a space craft, toward a brightly lit room in which I knew there were aliens who were going to do unspeakable things to me, and I was screaming but nothing came out. I would have only been about 3 years old. I wonder if other people have had that same dream, and then woken up convinced they were abducted by aliens in the night. Dreams are so frikken cool.
