I don't usually get "ghostly experiences". This maybe as far as I remember my only one or at least the only experience I can think of at this moment. But honestly and truly undoubtedly I believe in ghosts, spirits.
This happened when I was in third grade. I was sitting in class doing my work when I got this really strong feeling that I should look behind me, so I did. When I looked back I saw a shadow. It looked like my mom's uncle Nick who died I think about three years earlier. I couldn't believe my eyes. I didn't think it was possible. I blinked and he was gone. Four of my friends had been looking in the same direction I was looking in. I asked them if they had seen anything, they all said that they had not seen anything but the windows. I got really freaked out. When I got home I asked my mom what she thought of my "ghostly experience". She thought that I was either tired or just making things up for attention.
Even though I was absolutely positive that I saw my mom's uncle then, now I'm not entirely sure.
Please tell me what you think in your comments.
