I think I have ghosts attached to me. Idk what’s going on but it’s just getting more intense. Read below for details.?

It all started when I was like 10 or 11 and I was in my basement. I looked over and saw someone who resembled my grandpa who had been dead for many years. I didn’t understand since I didn’t beleave in ghosts then so I asked my parents and they were really surprised that the description was spot on from what I saw to what my grandpa looked like. So where all this picked up was I’d be trying to sleep and like I would look up and see the same figure I saw back when I was 10 or 11 standing at the foot of my bed. It had no face this time just was a figure. What ever it was has also woken me up once at 3 am. Someone was taping my shoulder and telling me to wake up. I opened my eyes and took a quick glimpse. They did not look like my parents. I described it to my parents and again they think it sounds like my dead grandpa. It’s gotten to the point where I have seen several things and my friends have even reported seing the same things to me. Not many people beleave me like it just feels as if many sprits are here and idk why. I don’t beleave that much I just am wondering why all this happens. I would like to know what to do about all this. Thanks :)
