That's why I made the remark about drugs, alcohol or hypermobile sleepers. My current wife, myself and my ex-wife never had an issue before babies, during and after.
It's actually not something I do while _asleep_, but when groggy. If I wake up in the middle of the night and decide I want to sleep on my side now, my sense of spatial awareness is pretty poor. I believe people can get by without issues, just thought I would pop in with an amusing anecdote :)
