I just had a dream last night where a strange, purple beam of light tentacling (that is to say, emitting out of in a tentacle like fashion) out of the distance constantly flop flopping the world around me and occasionally me myself. It'd go from an island party hot spot , like a boardwalk spanning a narrow island, and a mellow amusement park surrounded by trees. It would effect the people too, bringing their personality to the other extreme. Calm people were wild, the parties mellowed out, and I went from quiet and contemplative to outgoing and quick witted. What's stranger is that I do believe I've had this dream before, recently even. Except all the other times I hadn't been effected by the purple beams of light.
I also have reoccurring apocalypse dreams where the sky is red, has a dark red X in the sky, everyone is gone, and I am paralyzed laying in the middle of a road.
And a one shot dream that I still remember where I was alone in an aquarium and a shark busted out of it's cage and chased me down a hallway. This was repeated though by a Wolf in another dream, but the wolf never actually escaped.
I've also had dreams about playing the Super Smash Bros. sequels long before their release. Which is wrong all together because as they are great, they were probably 20x better in my dreams. Also I always had a long line of people lined up to play them, like I had an advanced copy or something.
