yep. me too. I suppose it's a way for your brain when non lucid to rationalize the weirdness you see?

In the past I've experienced things from looking at some stranger in my house and just assuming 'oh that's cousin clyde visiting for the week' (I don't have a cousin clyde) to the even weirder in my opinion, seeing my long dead pet hamster and thinking 'wait I thought he died years ago...oh no, wait that was just a dream!' (That's right I remembered reality but thought it was the dream!)

Most recently, I had a dream where I had friends over at my apartment. One of the guests was a girl I'd had a crush on in highschool. I had inivted her because she was girlfriend (as far as I 'knew')...but she was never actually my girlfriend, nevermind the fact that I havent seen her in a couple years either...

A footnote about this dream, my most lucid dream experience, is that I became lucid when I noticed my face in the mirror. Yes this is a common dreamsign so in itself not weird...but even when i became lucid I didn't notice something as obvious as 'hey wait a minute I'm not dating her!'- Not until I awoke. Ain't it weird what causes us to becomes lucid and what doesn't? Wow. me ramble lots.
