I had a dream that I was walking through a long hallway with red doors on both sides. At the very end, one door was open, and inside there was a table with a black envelope on it.
When I woke up, I remembered the envelope clearly because my name was written on it.
Later that day, I went to work like normal. Nothing strange happened until lunch, when a coworker handed me a black envelope and said someone had left it at the front desk.
It had my name on it.
Inside was just an invitation to a local event. Nothing mysterious, nothing scary. But I had never seen that envelope before, and I had dreamed about it hours earlier.
The hallway in the dream still bothers me more than the envelope. It felt like a place I was not supposed to remember.
