Mx M or NB Sleep Paralysis Demon plot idea

[DiabolusTarui]

This'll be my first time laying out one of my ideas on here so please bear with me! But I've had this stuck in my head for awhile and I'd appreciate another experienced literate rper to help me flesh it out a bit more! The idea is that character A has frequent encounters with a sleep paralysis demon (this can be from childhood or a recent occurrence). Then suddenly things stop for awhile which at first he thinks it's a good thing but then he realizes that hes actually been waking up feeling LESS rested than before. I figure we can discuss more plot points from there and I'm 100% open to this having some nsfw mixed in there once we get a feel for the direction of this rp. I have no preference of which character so feel free to choose the one that feels right for you! I'm more confident in my ability to rp MxM but this is a sleep paralysis demon so I feel like it only makes sense that theyd be nonbinary? Oh well, if this sounds like fun to you please shoot me a PM so we can discuss!
