question about flash backs?

[greg m]

Ok this is gonna sound weird but i have thought about this my whole life and im finally asking about it. When i was a little kid the first memory's i have i don't believe is mine. It was a series of pictures it looked like but each one had small movements. Some of a baby, some of people, etc. Well The last one i remember clearly and it seemed it lasted forever. It was a little girl in a pink dress, black hair, black shoes, and a pink ribbon in her hair. She was riding a horse and the girl couldn't have been more than 5 or 6. Well this one had audio per say. Some one said "Look chasity look! your doing it your riding cola". Well then i heard my name and then a big white flash kind of blinded me and then i was standing at a door with my hand reached out for the knob. I didn't know where i was who i was or anyone around me. The person who called my name said i had been standing their for a few minutes. Well i was only 3 or 4 at the time and so when i was 13 i asked my mom if we had a horse named cola before and she said yes. Well i already figured out that the little girl was my big sister chasity which is 12 years older than me. We had cola before i was born and got rid of him before i was born. So any ideas people. Is it possible to have some memory's from my mother.
