Is it possible reincarnation exist (I have strong aversion to large dogs)?

I have no real explanation of why I've always (since I was a toddler) been afraid of large dogs, esp Mastiff types. Plus I've always avoided parks too.

I used to have recurrent dreams that I'm an 8 year-old boy in the late 1970's (I was dressed up differently) that was out walking in a park and two large dogs attacked him and killed him. The dream feels so real, as if I've lived it before, as if I know what it feels to have your skin torn off by an animal, the pain, the agony, the masive blood lost and then you're dead. I started sweating profusely after waking up.

Is there some possibility that there is some truth to the existence of reincarnation?

My own parents and others relatives in my family confirmed that as a toddler all the way till I was 6, I used to tell them that I died of a dog attack.
