I had a dream about my colleagues Ex.

I have a colleague who I am in college with, and when we were in college her then boyfriend and I were nearly perfect strangers. Eventually she graduated- he ended up coming to my college- and we kinda hit it off. I have NO idea if he is bi, but there’s some stuff I just can’t get out of my head.

When we had met for the second time this was shortly after they had broken up. I was getting a drink from the water fountain which is right by a flight of stairs leading to the bottom floor- I think he was being funny- but he grabbed my leg hiding in the staircase walked out having successfully pranked me and just gave me a hug. He kinda backpedaled and said “sorry I don’t know you that well yet- my bad” I told him it was fine and brushed it off.

Since then our conversations have been relatively few- but last night I dreamt about him. It was “one of those” and holy shit. Now I know in that dream I’m technically attracted to my own brain- but I’m awake now and those feelings for him are there. Every time I talk to him he’s genuinely so sweet to me in a way I don’t see him being sweet to other people. As far as I know he isn’t openly bi but I don’t really know how to ask without embarrassing myself. I felt that way before the dream. But after I feel like ignoring it is gonna damage my mental health.

How should I go about figuring out his orientation subtly and then gauging again whether or not he is in to me?

Note: I am autistic so that’s why all this is particularly difficult/confusing.
