Strange happenings around house

Well for starters I’ve been keeping tabs on everything happening. Let’s start from the top. I went to 5 below and bought my daughter a red light green light (Squid Game) toy and late at night around 3am it turns on by itself. Only way to turn it on is removing the battery cover, pressing a black power button, and pressing a button on the wireless remote. It has happened 5 times over the last 2 weeks. I’ve been seeing dark shadows moving around my room in the darkness, peeking around the corner thru the doorway by her room. Feeling cold breezes and having random lights turn on or off by itself. Am I going crazy? This all has been going on for a little over 6 months.
