Where did your friend find that "fact"? I've read the opposite, it's very common for people to have sex dreams featuring people of a different sex than they're normally attracted to, and the reason is because dreams are not literal desires. Having sex with someone in a dream doesn't mean you secretly want to have sex with them in real life! Symbols in dreams are very individual and vary by culture, but generally dream sex just means you want to be closer to that person. Or it could mean something else, but only you can decide that.
I have sexual dreams very rarely, and I've never actually had sex in a dream. When it happens, there's generally a "fading to black" moment when the dream turns to something else, but I knew me and the other person were going to have sex before that. And the only people who've featured in such dreams have been my friends, both male and female. Needless to say, I don't have any desire to do anything sexual with any of them. When it happens, I'm usually like "oh, one of them again? Ok whatever."
There was one case of a dream where a guy I liked showed up and put his hands on my shoulders and pushed me backwards. In my dream mind, I knew something was going to happen, and my heart rate sped up in response, which unfortunately but unsurprisingly woke me up. How does anyone even sleep through sex dreams with someone they like???
I can't answer the poll though because I'm not heterosexual.

Children don't worry what they look like to others. They are 100% themselves. When we get older, we learn to fit in society by submerging those parts of ourselves that our culture looks down on. We don't want to be rejected by our parents. We don't want to be rejected by our peers. Growing up may include re-embracing ourselves even if we must stand alone.
Thank you for being here as I re-embrace the Self I'm meant to be.
