SORRY FOR ALL THE ANNOYING NEWBIE QUESTIONS I ASK.!!!!!!!

yeh, now that i have had nearly a day to think about it, i could just be dreaming i had the beanie on..and many other things... sorry... i just dont quite understand when someone says "Do a reality check" i know they mean to see if im dreaming but "How do i do a reality check?" in waking life? i've read them all but cant grasp on how to actually do a reality check. just look in the mirror every hour and say " am i dreaming"
etc , i dunno the only thing i would most likely pick up on is if i was dreaming and i checked me wallet and i had lotsa money i would KNOW i was dreaming.
I CANT WAIT TO GO TO SLEEP AT NIGHT......
