The strangest dream ever

Dreams always has been a mistery to me, they took my attention and makes me think about how our brain works.
When I was a little girl I used to dream with a snake, this snake was huge, I think that was because I saw the Anaconda movie, but this big snake it used to be eaten my mom.
This dream repeated for a long time in my childhood, I've never know why, but I though it was because I was always afraid of been abandoned for my family, I was so paranoic with that.
Honestly, this dream scared me for a very long time, even I thought one time if I was adopted, and asked to my parents crying hahaha my mom and dad they didn't know whether to laugh or cry, it was a very bad moment, but my mom trying to calm me down show me my birth certificate and show me some photos. After that I could sleep well and I never dreamed that dream again.
