I remember everything when it's personal and holds importance. I've had reoccurring De ja vu since a child. I still get it. Just not as often.That's what I thought. It's not bad or good, it's just the way we are. Don't assign too much value to it, just know you are the way you are and you are not alone. You had no choice in it either. You responded to the environment you were in and developed into who you needed to be to survive. The brain will erase one's memories so they don't go crazy with trauma. Do you remember your childhood in connective streams or spots?
For example, I only remember parts of memories. I remember very little of my childhood and it's all a blur with the occasional clear incomplete picture. On the other hand, I can remember food orders from 3 years ago. I can tell you what I wore on a date years ago. I remember conversations word for word without trying to memorize them. It's how the brain copes with severe trauma as a child, since it can't make sense of it, it will erase it. It's crazy.
Dreams aren't always dreams. They can be memories we forgot. We can't escape ourselves though, so these memories show themselves when our subconscious brain takes the lead. During sleep, being high, when we're worked up, etc.
I dated a girl who fought in her sleep. She had no idea why. She fought hard in her sleep. She only chilled when I hugged her hella tight. She'd grab me back or scoot real close. Then be still. She didn't even know she did it. Later she remembered she was sexually abused by a family member. It didn't stop until her mom re-married and she got a big bro who protected her.
I'm a very nostalgic person. I can remember details and specifics to things others forgot. I can place people and familiarity. I'm really good with placing faces and studying features/faces. I can tune out things rather easily and naturally however it's a choice. At the same token if something is traumatic to me or someone couldve done something to me many years ago, I'll always remember it specifically when they think its over and done with. Especially if they didn't right their wrong in a way I'm satisfied with. I hold serious grudges. I've been trying to resist them because it's not healthy and it's toxic.
