I don’t know what to do

started this new job a couple weeks ago now and I’ve really enjoyed it. The other night I decided to go out with one of my male coworkers after work (he’s 60 and I’m 25) I kinda looked at him as like a parental figure. I woke up in his room ( fully clothed ) but he was laying there cuddling me. I know I didn’t do anything sexual but I feel so uncomfortable going back to work. I don’t know what to think of the whole situation when I woke up to an old man touching me . I asked him about it and he said “ I was going to try to walk you home but you couldn’t walk so I just put you to bed “ but waking up to him cuddling me was definitely unsettling
