Desperate to escape the grip of heroin addiction, Lily agrees to an experimental treatment with a new drug called Deimosimine. But instead of liberation, the substance plunges her into a nightmarish reality where blood and horror bleed into her waking life. As sanity fractures, she’s forced to confront a terrifying question: is she the helpless victim, the monstrous perpetrator, or both? Deimosimine is a visceral, mind-bending journey into the darkest corners of addiction and identity.
User Reviews
“The atmosphere is thick with dread, and the lead actress really sells the descent into madness. Some parts dragged, but the ending left me thinking for days.”
“Brutal and unflinching, this one gets under your skin. The practical effects are awesome, and the concept of addiction as a monster is brilliantly executed. A hidden gem for horror fans.”
“Interesting premise, but the pacing felt uneven. It's more psychological than scary, but when it hits, it hits hard. Good for a slow burn horror night.”
“I appreciated the mix of body horror and psychological terror. It's not perfect, but the unique take on drug addiction and the claustrophobic vibe really worked for me.”
