strange happenings in our home

We've experienced some strange paranormal activity in my youngest daughter's room. A few weeks ago I noticed some strange ink markings on her bed, on her dvd player and her pillow. The strange thing is no one seems to know where they came from. Any ideas? Could this be paranormal activity?

Your girls are such sweet little angels, I am sure if they claim not to know how it happened then it was probably aliens, or ghosts...or druids!!

I would recommend making her wear a hat made of tin foil (or a metal collander if you have it.) This should keep the aliens from taking over her mind with their evil microwave ray-guns.
