For years I've been randomly experiencing false memories within my dreams. For instance I will be in the middle of a dream and then straight up 100% remember something funny a friend said the day before, and then I'll wake up and realize that shit never happened. I get all types of memories, sometimes even about people I've never met that I made up within my dream on the spot. The crazy thing is that these "false memories" are coming straight from my memory center in my brain, they feel completely real until I wake up. Memories are imprinted in your mind. You can shine a light on a dark wall and see something you did years ago, and the proof is the impression left in your mind. But how can your mind just fabricate impressions like that on the spot? I've always been a semi-lucid dreamer, like I know it's a dream but I don't yet realize that dream reality isn't real reality, so I don't have complete control but I'm usually pretty clear headed. This makes these instances even more trippy. I also experience deja-vu in waking life relatively often. While the fake memory in the dream feels straight up like an actual memory, deja-vu feels more like a foggy memory is being channeled to you somehow for 5-10 seconds and you get the crazy feeling like this has happened before, and then it's gone. Maybe they are related? Similar experiences?
