Paranormal: Real Ghost and other entities on the internet

No and I don't buy that your friends contacted them through electrical equipment of any kind. Don't misunderstand me, I do believe in ghosts and spirits as I've had several encounters with them in my life, but I don't believe that you can contact them in a chat or via forums or cam, as your question reads. I have had a ghost that was tapping my foot when I was trying to go to sleep. I had just moved in with some friends and was in bed, trying to go to sleep and I felt something hit my foot. I looked up, but nothing was there and my niece who was also in the room, in bed too far away from me to have done it was fast asleep and snoring like crazy. It wasn't completely dark in the room as there was light coming in through the window from the street light outside, so I could see pretty well. There was nothing there. So I thought it must have been my imagination and I tried again to go to sleep, and it happened again. So I changed my position in bed and drew my feet up. Didn't happen again that night, but the next night, same thing. After 3 or 4 times I finally just said, "Would you stop it? This is my room now and I have to work tomorrow and would like to get some sleep. You need to go now." It never happened again after that.
