No Sex Drive but I Keep Having Dreams About Sex

Ladies I need help! I have absolutely zero sex drive. Like, NONE! I have been with my man for almost 4 years, our sex is good when we have it but I have zero interest in it.

Well, for the past 2 weeks I have been having dreams about sex with random other guys (twice was my ex, one was gerard butler, one was Billy from stranger things lol) and one time I remember waking up orgasming but I dont remember who/what that dream involved lol.

So does anyone have any ideas what these dreams could mean?!

Side notes:

I am 26

My sex drive hasn't been good since I was in high school.
