You ever have a shocking and disturbing experience you can't explain

The guy that owned my parents house before I was born was named Mr Hopper. When I was about 13 years old I was home alone and he knocked on my door and told me he used to live there but left some tools in the garage. He seemed very nervous, almost distraught. Mind you this was about seventeen years after he moved out. I didn't know what to do so I told him to hold on while I called my mom. My mom answers the phone and with some alarm in her voice told me Mr Hopper committed suicide years ago and whoever this guy is don't let him in the house or garage. I thought Mr Hopper had died but didn't know he committed suicide. Inwas terrified to go back to the front door but when I returned he was still standing there. I told him my mom said he couldn't enter but to leave his phone number and we'll call later that day. He looked disappointed but shuffled off innocuously enough.

When my mom got home she wanted to know what he looked like, how old he was, etc. My description seemed to match someone that fit Mr Hoppers profile. After dinner she calls the phone number and someone answers but says nothing on the line. She hangs up and calls again, and again the same thing. Someone answers but no one responds. We were both creeped out and I had to sleep in her bed for a few days before I felt normal again.

A few weeks later my grandmother manages to get in touch with Mr Hoppers widow to see if he had a brother or someone that would have shown up at her house. She was apparently very upset by this conversion but had no explanation. Just a creepy experience.
