I believe you Niamh.
I messed around with some friends on a ouija board as a kid (early teens) and it freaked me out so much I never did it again. I felt physically sick after we did it, really ill and headachy, and so did the others. That night I went downstairs for a drink and opened the cupboard to get a glass. The glasses were right at the back of the cupboard so couldn't have been dislodged by me opening the door, and the glass we used flew out out the cupboard into midair, fell to the floor and smashed.
Never again!
