When doing the RC by asking yourself "am I dreaming " and then pulling my hand infront of me and looking at it in a way to see if something is different to it... What am I better of saying as mantra while looking at it?

"I am dreaming "
Or
"The next time I dream I will know I am dreaming"?
And what am I suppose to pretend to feel while saying one of those mantra and looking at my hand?
