Ghost? I might sound crazy y’all!

I was in my room awake but with my eyes closed, my husband was downstairs and my 4 year old was in his room just waking up. My sons room and my room share a bathroom so I keep the doors open so he can come wake me up when he gets up. Well I hear him talking and then I hear his money in his piggy bank moving around. I thought to myself “oh he’s probably bringing it in my room to count the money”. My son came running full speed into my room empty handed so I told him “oh dads downstairs” and he told me “mom my poop emoji piggybank was wiggling!” He then proceeded to tell me he was in his bed waking up when it happened. I heard it too from my room moving around so I know he wasn’t just still groggy from waking up. 👻
