I can tell when my memories are real versus what someone has told me because the real ones have a sense of realness to them. hard to explain.

like for instance some telling me about a car accident I can know the basics but not the actual feelness of the emotions, textures, sights, sounds, tastes, smells, and so on - example I know the car was red and it crashed and abulance came and so on in the words of someone else.

realness. seeing the other driver coming at me. the fear and adrenalyn as I realized the car was going to hit me, the part of the car that my eyes were drawn to, the smell of the rain on the street, the sound of the car hitting me, the sounds my body made when I hit the street, the feeling of the bruises and cuts, The feeling of being floaty and dream like as I got up and pushed my bike off the street, the static in my head as the woman was asking me if I was alright ...... the list goes on.

If the memory is made up there will not be any sense of automatic realness to it.
