Hey! My question might be a bit weird, I'm not sure, but I was wondering if this is common or has an explanation. I have a lot of dreams/nightmares that in the middle of it I have that "deja vu" feeling and remember already having dreamt that, sometimes multiple times (though not being in a lucid state), but when I wake up I realize I never had that dream before. I'm curious about that cause after a while I start to doubt myself whether I really never had that dream before or if I just forgot about it. For me it's more common to happen with nightmares.
