How old are you?
It's quite common to sleepwalk in your adolescence.
When I was a kid, I went down stairs, out the back..up the garden, over the little bridge over the pond, stood around for a bit then went back.
All fast asleep stark nekid...witnessed by my big Sis whose bedroom was down stairs, she'd been woken by the noise

Like you say, lucky there was no machinery involved... I had a Lambretta scooter at the time.
I certainly dream about bowmaking...
