Is it normal for my brain to forget things but my hands remember
Ok so my question may seem very weird but I have a crappy memory at the age of 18. I have these moments maybe once or more a week where let's say I want some water so I walk into my kitchen but then I forget what I came in for and all of a sudden my hand is making a motion like I'm holding a glass and bringing to my mouth to drink then I'm like right I came in here for a drink. It's so weird I do it for food too except it's just my hand going to my mouth and my mouth makes a chewing motion. I don't forget what I want Everytime I go into the kitchen it only happens rarely. But is it normal for my body to remember what I'm doing but my brain has no idea what im doing
