Recurring childhood dream

Date: 7/12/2017

I don't know the exact years, but when I was a kid(elementary school) I always had the exact same dream when waking up from my naps at my grandparents house. I had to have had it at least a dozen times. I'm strapped to a wooden chair in the middle of a concrete, gray, featureless room. There's a naked bulb hanging on a chain, and a lone doorway, too far away for me to get to. I want to call out for help, but there's a gag in my mouth. Then someone enters. It's a giant sumo wrestler. Several more follow behind him. Some are in the traditional sumo outfit, some have normal clothes. All of them begin to close in around me, then poke me endlessly with toothpicks. It tickles and hurts, but I can't get away. I can't scream. I start to feel like I'm suffocating as they all press closer and closer inward. Eventually the prickly sensation wakes me up.
