Intruder is a monster from a dream I had.

"Intruder" is a dimension hopping monster that hunts in our realm. He breaks into people's homes; looking like a normal human at first but causes a wave of clouded confusion making the victim not pay much attention to his presence until he's ready to make his move.

A person who's home is infected by him will feel very dissociative and have hallucinations of things like tails quickly turning the corner or bright white eye shine looking back at them.

He can only cause this confusion in his human disguise; so right before he transforms into his 'true form' (seen here) the victim realizes someone is in their house and has only seconds to react before being hunted.

I jokingly call him Blorbo(derogatory) because the dream I saw him in was very frightening lmao.
