Had a good set of dreams last night, none lucid (I tried)

I had a very real false awakening in which I proceeded to do my daily routine, however I kept saying to myself "this has got to be a dream". I went around my house checking stuff out for any descrepencies to reality and eventually made my way outside where I saw my mother taking out, wetting and laying down wallpaper all over my father's motercycle with a giant paintbrush. Yet it didn't click heh, doh

what are some of your obvious but missed dreamsigns?
