Reality Check Failed? :( Ld4All

Hey everyone!Okay the nearest i get to lucid dreaming is Friday night/Saturday morning because of no school so i always seem to get close/have a lucid dream at that time.Anyway so last night i was dreaming and i thought "is this a dream?" looked at my hand and it was normal, looked back at it again still normal ( i forgot about other reality checks) and i thought oh must be awake, then a few minutes later i wake up in my bedIs it often that the hand check fails?Anyway next time i will remember to do more than one reality check!
