One time I had a dream where I woke up in the middle of the night to my sisters upstairs screaming and getting cut off, then a bright light seemed to lower from the sky shinign brightly into my room. So I got up and in the living room saw aliens floating my mom and brother through the wall. I jump attacked them but they pulled out something with two prongs that made my muscles tense and relax, but in a shockwave kind of way. I fell down on the ground, got up and ran a few steps but all the strength left my body and I fell down again and slammed my head on the ground but didn't feel it, and things faded to black as they approached.
Then I woke up still inside the dream it was like a a normal day... an entire, completely normal day in it's full length of time. My family didn't remember anything and I didn't say anything, so Iw ent through the day and I went to sleep inside the dream and had a dream inside the dream, woke up still inside my dream and had another full day, then another night, dream-inside-of-dream and then woke up for another full dream-day. Through each day I had headaches that got worse and worse, towards the end of the last day I got one so bad I was disoriented and fell out of a window.
Just before I hit the sidewalk I woke up for real. But when I opened my eyes I was falling into my bed from 2 or 3 feet in the air and it bounced me all the way across the room. I was really confused and didn't know what was going on, I tried to replicate the bounce but couldn't get the same distance. I was really messed up and didn't know what was real for a few weeks after that but I didn't tell anybody.
Then on a more serious note...
Another time I woke up and my mom and brother were watching the news talking about how a plane had flown into a WTC tower, then another one flew into the other tower, then a bit later the pentagon had a firey hole in it. That was pretty messed up.
