Obsession

"She's sleeping. It's me." it's a total nightmare scenario. her brain is literally functioning normally in the background like "what the hell am i doing, this isn't me", but her body is completely hijacked by that supernatural curse. she isn't even aware of it all the time, which makes it worse. those sudden moments when she snaps back to reality and realizes she has zero control over her own hands or arms, screaming inside in total helplessness... those mental breakdowns are seriously terrifying.
