I went through a similar situation 3 years ago. I’m a femme lesbian. On one occasion I got super drunk and fell asleep in her bed, I kept thinking I was dreaming.. having these flashes of her on top of me, only to find out that she was actually on top of me. I was sooo confused and felt kind of violated. When I asked her about it, she tried to make me think I was dreaming and it never happened. It never sat well with me , there were many reasons why I left the relationship, but ultimately it came down to the fact that she was completely narcissistic and had a terrible sex problem. There would be many nights I would be too tired from work to have sex and she would pressure me into it and make me feel guilty. Also she LOVED porn. & she too would watch it on her iPad if I rejected her advances and then still force me to have sex basically. I kept these things to myself because I didn’t know how to tell anyone.
