One of the wildest theories from Obsession:
Nikki isn't just obsessed with Bear... she IS Bear's dead cat.
Think about it:-
• She hides in corners and watches him sleep.
• The way she moves feels almost cat-like.
• She waits by the door for him all day.
• Her glowing eyes in the silhouette scene mirror a cat's eyes at night.
• She literally brings dead things to him, just like cats bring "gifts" to their owners.
The theory says that when Bear made his wish at the One-Wish Willow "I wish he loved me more than anyone in the world" his dead cat's spirit was nearby and entered Nikki.
After all, who loved Bear more than anyone? His cat.
Rewatch the movie with that idea in mind, and Nikki starts feeling less like a person... and more like a devoted pet that became something much darker.
You all gotta learn to raise your voice. At the very begging of my Backrooms showing someone turned their flashlight on and it hit My face and I very loudly just said “turn the light off.” Whole movie it was silence. From everyone. Set the tone.
