You're a detective and you're in the middle of an investigation till you saw your strange neighbor looking at something in the dark, you found it quite ominous so you came to check and what you saw wasn't even human, or atleast not anymore.

This wasn't your first time seeing this but it seems that you only see these things with him. He turned around to you slowly,

"You... See them too?"

He asked like this was a normal occurance.

This might help with your investigation, what will you do?
