I am losing my mind

About 6 months ago my friend had told me a girl we both know of came out as a lesbian... that night I come home and have a dream and Reese Witherspoon trying to kiss me. Now I can’t help, but think it’s my subconscious self telling me I might be gay? I clearly have no feelings for women and am happily involved with my boyfriend... but why am I having lesbian dreams? Is that normal? What does it mean?

Side note: I did not participate in her advances either. I was rather taken back and told her no in my dream🤣
