There's two kinds. There's the ones about the YouTuber, and then there's the valid ones, when you only have sexy feelings and genders in dreams.
Only the second one is valid
it really depends on what kind,
the youtuber dreamsexual/dreamgender is a negatave responce
the sleep (which i don't get much of) dreamsexual [u get horny from your dreams]/dreamgender (which i know NOTHING about) is a positive (but needing to clerify) kind responce
