Hahaha no need to question your sanity! Wouldn't dreaming be kind of boring if nothing special ever happened without any logical flaws and irrational things?!?! I have had the craziest dreams and those are usually the coolest and most vivid.

Oh yeaaa who doesn't know this...? Writing down a dream in your dream journal and just being unable to grasp how much you just passively ignored all those impossible things that happened... "Oh yea flying fish, pink dogs, thousands of snakes in my room. Seems to be normal so I'll just forget about it and definitely not do a Reality Check as if nothing happened." - Crazy isn't it? One more proof that awareness really is the key for lucid dreaming! Noticing things that are out of place makes lucid dreaming so much easier.
