I think I am psychic but am not sure?

So I've been having these weird encounters with friends or people I know. It started a couple years ago where I could feel the pain of my friends then I would ask them about it and they would answer that they are in pain in that area, then it eventually changed into I could smell what was around them or like taste what they were eating or drink. So if anyone could maybe help explain or give insight that would be helpful.
