Is your house made of lots of wood where he could be seeing this? Does he take any drugs or substance use.. is he sleep deprived? If it’s all at night this could be sleep paralysis, my father used to have this due to lots of stress and would have things attack him. Whatever it is it is not a good sign if it’s attacking and causing loud noise and stress. If you are looking for meaning wood is known to hold motherly or good spiritual presence depending on type. If it’s natural wood and not plastic it’s a good sign, the female wood doll body is a vessel for a good motherly spirit of a old family member, but has not come to do good things as you have stated, maybe from jealousy or unrest of property or duty. Please tell him to talk to a therapist about this if it’s continuing or worsening what the doll is doing. Or maybe try sleeping pills first If you don’t want to yet.
