A lot of people have had striking pre-cognitive dreams. I only mention this because it has happened to me once in my life, and I'll never forget it. I had a dream that I went to visit a stranger's house and he gave me and my friend a tour. Some months later, my friend said someone he knew had offered him a job in Utah and I was invited. We drove a U-Haul over there across a few states, and when we arrived the man gave us a tour of his house. The same tour from the dream.
I'll never forget this.
That isn't psychic ability, that's a precognitive dream. Being psychic implies the ability to do it at will. These dreams one has no control over.
So yes it is possible to have a minor insight into what the future holds, but no that's still not psychic ability.
Which btw is off-topic... We're talking about a psychic winning the lottery and retiring, and being labeled as a scammer.
