Using an Ouija board in my friends trailer, had appliances like microwaves but no power or anything, so when we trying to ask the spirit to make contact with us it didn't so we decided to just stop.

My friend threw the board on the ground and right after his microwave which had no power went on then back off, we used the board again but I am pretty sure my friend was pushing the key around the whole time, but at the start when we had to summon a spirit to communicate with I summoned the spirit of Bloody Mary and no one slept that night
