this is my 3rd lucid
i was in a field and i floated down a hill and went past a few people. then the wind started to catch me and i was flying kind of, like i was moving with the wind in order to go in the direction i wanted. i ended up trying to land on a building and i hit a amusment park ride.. rollercoaster most likely. i wasnt fuly lucid at that point but once i hit the ride i did a reality check pluging my nose. i couldnt breath. so the reality check failed. but luckily i fell to a river and on the bottom it was flat like a linolium floar so i became lucid. i flew around some more then i wanted to find some people so i went into this house. the rest is kind of weird so i wont say.

my question is why didnt that reality check work. and why did i become lucid right after i did it. is it the fact that i managed to do a reality check in a dream?
that was the first time ive done a reality check in a dream btw.

another thing, in my lucids my soroundings arent very stable. their always changing is there anyway i can change this. like i will be in a room and i turn to look one way and a portion of a previous dream will show up in that part of the room. i seem to forget to rub my hands together if thats the trick.
