Ouija Board?

Has anyone used one? My friends and I used one Friday night. They stayed over and the night went on normally. Last night, not so much. First off, my son got out of his crib, opened his door, the came in my room and just stood there with his blanket. I could here the baby monitor he was up so I was up and what do you know my door opened. He stared after I called his name over and over. (He's 18 months) I picked his up, made a bottle and he went to bed. Freaked me out. Later the same night our garage door opened. I have an alarm when it stays open to remind me to shut it. I go out, shut it, come upstairs and the baby gate is locked. It doesn't just lock on its own. Then I go into bed and about 20 minutes later out of nowhere my dog starts barking at me and nipping at me and he would NEVER do anything like that. He never barks. Please tell me this isn't a bad sign???
