I had this dream several years ago. It starts out with me riding a dinosaur on the perimeter of a small island. I was holding this wooden club, chasing a tyrannosaurus. The bright blue sky and glistening ocean water are in my peripheral view. The dinosaur I was chasing turns around suddenly, causing the dinosaur I was riding to fall over. Now I'm falling into the ocean water... except the water gives way to nothing but blackness. I become aware of myself from a third-person perspective, but am still experiencing this in first-person. My body falling, forever. I try to say something, but can't. I try to move my arms, but can't. My body begins heating up, rapidly, and I feel that. Despite having feeling still, I can't move at all.
Then I woke up. That's probably the only "falling dream" I've had that I can recall.
I had this other weird dream after playing through Rewrite. (Rewrite pseudo spoiler / dream) I'm walking through a college campus. There are people all around. It comes to my attention that the landscaping was redone. A new tree has been planted with a type of berry in it. As it so happens, I'm hungry. Reaching out for a berry, my hand brushes against a leaf. I pull the berry down, with this strange sensation in my head... The leaf gave me information. A strange nostalgic feeling... Who cares? I ignore it, because I'm thirsty. I drink some water from a water fountain. Someone bumps into me, causing me to spit out the water I was drinking.
The person who ran into me is running. Why's he running? A girl is with him, and they're running together. Curious about this I run toward them. We keep running for quite awhile, until we reach a rural (almost steam-punk style) part of town. There's hardly anybody here. Just a building made of rusty metal and rope, its structure difficult to describe. I catch up to the guy, but the girl is nowhere to be found. "Where is she?" "..." he turns to me without saying a word. His body turns to ashes, it seems like. From the strange building of rope and metal emerges an angry dog. It's growling. Then it starts chasing me. Naturally... I run.
A house enters my view. There's a bus outside of the house. Some friends I know are loading the bus with weapons. I head inside the house to do the same. Upon returning from inside the house, the bus is gone and only a few friends remain. They are no longer alive. The dog from earlier, somehow larger than before, is sitting still in front of the house. A girl, seemingly the one who was running earlier, steps over from behind the dog. "You're the tree. You control this world."
At that point I realized I was dreaming and woke up. (That seems to always happen just before I lucid dream...)
Okay, and one more (short) dream. This was the first and only time I've ever lucid dreamed. Let this serve as a cautionary tale.
I'm sitting in my lawn, by the sidewalk. Several men in McDonald's suits show up with heavy weaponry. This war veteran shows up next to me. "I've got a 'nade, it's alright." He throws the grenade. Realizing that this is very unlikely to be happening, I make the connection that it's a dream. So I stand up. "It's a dream, I can do whatever I want!" And I grab the grenade. The soldier guy looks at me strangely. Then I realize that the grenade can blow up. And it blows up. Then I woke up, so shortly after assuming control.
So, don't do something crazy right away, I guess.
