sleep walking while pregnant

So currently 8 months pregnant and this is al new for me I've noticed that I've been doing random tasks at night like starting laundry, replying to clients emails, and ordering stuff online with no recollection of it the next day :( I know insomnia is a common thing around this time in pregnancy but I don't think doing tasks without recollection is. I'm just wondering if anyone ever did something like this while pregnant? 🤰
