It's a dreary day and I'm bored...Give me your best real life ghost story!

Let me preface this by saying I'm not so sure I believe in paranormal or life after death, but I have to admit there are some things I just can't explain.

For example, before my grandmother died she told me she had a dream that she was getting married (to my deceased grandfather) except she had on a black wedding dress with a black veil. A week later she passed away suddenly and unexpectedly. Last night DH and I were watching tv and there was a paper towel rolled up on the coffee table. It randomly started moving back and forth about 5 or 6 times before it came to a stop. There was no wind, no draft, and we hadn't moved at all. My grandmother popped into my mind and I thought to myself "Grandma if that was you make the paper towel move again." I stopped looking at it and honestly forgot about it. When the show was over I looked down at the coffee table and the paper towel was gone. I hadn't noticed, but it somehow ended up on the floor. As a test I picked it up and placed it back on the coffee table. I then took a blanket and waved it around, but the paper towel didn't move an inch. I can't help but wonder if maybe that really was her spirit....
