Mole excisional biopsy with stitches sleeping question

I recently got a mole biopsied on my breast. It was twice the size of an eraser, and required a few stitches. I had the stitches removed after 10 days, and my wound reopened a little so I have steri strips now. I'm just wondering if I'm okay to sleep on that side of my breast without harming it considering the wound opened. They didn't tell me.
