Hello, i'm a 65 year old man who was doing a little shopping at a local store the other day when heard this guy laughing next to me while looking into the frozen goods freezer. When he walked by me he said these words, "A voice told me to remember this face", I thought he had an earpiece and was talking on the phone, but he was speaking to me! At first I thought it may have been a classmate or co-worker from the past but l couldn't remember his face. I didn't feel scared or threatened just puzzled. Then he said," the only thing that I can tell you is God is good!" He walked away smiling and I was puzzled! After a minute or two, I walked up the aisles to ask this man some questions,didn't see him, looked outside, nothing! Anything ever happened to anyone like this before?
