What has been your most bone chilling “I have a bad feeling about this” experience?

I had a drama partner in HS we had to practice lines together. He gave me the creeps. I knew something wasn't right with him. He once pulled out a knife and cut my skirt and the look in his eyes was dead and bone chilling. Two weeks after that incident he beat an elderly man to death with a bag of coins he found in the man's house. I knew in my gut he was evil the first time I met him.

Hmmm. Only thing that comes to mind at the moment is when me and some friends were throwing water balloons and passing traffic and we hit a cop car. Wasn’t a pleasant experience at all
This was back in my teenage years

Not my experience but I remember my brother in law overhearing someone talking about poisoning his dad which long story short prevented something that could've been deadly.

When driving interstate with a air of so called friends, I felt like they had something else planned which involves “knocking me off”
The journey home, I survived an attempt on my life.

People lol
