Hello Dreamers! I had a dream the other night, in wich i was with some of my friends in my school discussing a new "lucid dreaming device". I was not lucid at all. I had no idea that this was a dream.
So we moved on and walked out of the school and crossed a road. And i suddenly stopped and said "guys whait for me, im just going to preform a reallity check"
And so i preformed the "plug your nose reallity check" and i could breathe through, but just a little bit (maybe because i have a cold and perhaps had clogged nose)
And just because i could breathe through so slightly i thought "well it is because im not plugging my nose that hard, that is the reason why i can breathe through". I did not att all consider the thought that i might was dreaming...

Why didn't i think that i was dreaming? Why did my reallity check fail?
Any ideas?
Thank you all!
