Done that as well. Sometimes when spelling out a word I've used everyday for 50 years, I stop and stare at it and think.... naw... too simple, is it really spelled that way? The word "been" comes to mind...
Presque vu - translated as "almost seen", this is the sense of being on the edge of an epiphany or realisation, for example recalling a memory.
We called them brain-farts.
Déjà entendu - translated "already heard", this is the sense of feeling sure you have heard something before, like a snippet of conversation or a musical phrase.
Would this be typical of annoying people who insist on finishing your sentences?
My favorite mind experience though is something that has been ongoing for 20+ years. I wind up in the same dream 2 or 3 times a month. I'm in this awesome house with a walkout lower floor that looks out across a bay. I feel like I consciously know that I am dreaming and tell myself to look behind the door that I didn't get a chance to open the last time I was there...
I keep a sketch pad nearby and when I wake up, I'll add some more info to my floor plan and even jot down a few reminders of other things to look for next time. I have a CAD program and have been building a little library of layouts. It would be pretty cool to build it some day. Even have a name for it if I ever take the opportunity to do so.
You win. That's pretty cool.
