Yes, I had a weird experience when I was in grade one.
It was the morning, and I was gathering pieces of Lego before school for some impending day in which 100 days of school had gone by, and each student had to bring in 100 pieces of something to share. While I was looking for Lego in my room, I checked under my bed and I instantly fell into what seemed like a dream like state. While I was looking underneath my bed, there appeared this life-sized marionette with a long chin and a pointed, curled hat, which made his head looked shaped like a crescent, with a white face and black clothes, who just starred at me as I gazed back. When I tried to move, by moving my head, the marionette would mirror my exact movements. Besides the slight movements from my head, it seemed I couldn't move or get up at all, as if I was stuck and completely immobilized. Just as this realization crossed my mind, the marionette instantly closed in towards me, like it knew I was vulnerable. But just as the marionette almost got up from underneath my bed, and closed right in front of my face, I felt a hand on my shoulder, which "awakens" me from this hypnotic state. I look behind myself to see what it was and the hand on my shoulder was none other than my mom's, whom then asks me what I was doing just leaning there on the floor. Then, when I looked back underneath my bed, that strange marionette was gone.
Might have been a ghost, could have just have been a daydream. All I know, I have never experienced anything else like it in my entire life.
