Misconception

When I was in elementary school, a friend of mine, possibly influenced by a ghost show they watched a few days prior, started saying they 'saw a ghost.' I asked them where it was, and decided to go there with a few other friends. It was a tunnel, so we decided to just pass through it. We were talking at first, but halfway through, my friends went silent and stopped responding when I called out to them. I gave up too and walked in silence. The path beside us was quite narrow, so we were walking in a single file (I was in front), but the footsteps I should have heard from behind gradually faded away until eventually, only my own footsteps could be heard. Feeling something was off, I looked back, and my friends weren't there. Looking towards the exit, I saw they had already gone ahead. Panicked, I hurried towards the exit as well. According to them, I started talking to myself halfway through and didn't respond when they called me, which creeped them out, so they went ahead, avoiding me. When I told the friend who initially mentioned the ghost story about this, they said they had no memory of talking about ghosts or even of the tunnel's existence. And it turned out the actual story they were telling was... about accidentally walking into the open door of the microwave. Hahaha
