Whoo!
I had one last night! I didn't even need to put an effort to it!
I don't really remember what kind of dreams I were seeing but I noticed that I was standing naked in the rain outside, near my childhood home. Of course, the situation was so absurd it made me think "is this real or dream", and then I suddenly felt very very weird, I knew I was in a dream! I almost woke up the same second, and it was very hard to keep my consiousness and focus, so it didn't turn into a regular irrational dream.
Of course, I went to have sex. Without much success though. Some weird things prevented me from doing it
Anyways, the feeling of being in a dream was just so fantastic I can't even describe.
Weird though, I tried running very very fast and taking like 5 meter jumps, in which I succeeded, but I got exhausted o_O Woot?
When I had ran around places for some time (without success in doing anything but taking a few 5 meter jumps) I felt that I am about to wake up. I tried fighting it, but somehow I knew that this was it. Then I just 'let my self go' and I woke up. It was 12 pm.
I really hope to feel this sometime very soon again, I've never felt anything this awesome!
It's the realitychecks that work! Maybe next time I'll be more successful in things like summoning objects, running fast or flying.
So it really can happen to anyone, even to the most inexperienced people. Don't give up and think that it needs years and years of practice, just keep doing those reality checks!
