I saw that homeless guy again today. This time, I gave him a few dollars. He didn't seem to recognize me.

But I recognized him. I've seen him at my work a few times.

Hopefully he hasn't been stalking me. One night about a month ago, I left work after dark and was waiting for the bus to come. At the bus stop, I saw a man walking closer and closer to me. I started walking towards a restaurant that was open to be safe from him. He followed me to the door. When I asked him where he was going, he said that he was going to the food pick-up door...That guy looked quite similar to the homeless man I just encountered.

I'm actually not too worried. But I'm wondering if I'm having hallucinations because what are the chances that that guy has been following me?
