I was in Krakow in Poland visiting the mecca of the Polaks with my mother for a couple days and there was this trolley line we used to get to the hotel from the train station. It was the 19 line trolley. One day I went to town on my own to purchase a pair of sneakers from a store and I took the 19 line to get there. All was fine and dandy. I came home and everything went well. The next day we were supposed to take the same line to go to the train station to go back to Legnica where I was staying. Me and my mother were walking to the the same stop I had taken the line from the day previous. When we got to the stop the 19 line was nowhere written on the stop. My mother kept saying how they change the lines due to construction all the time and that they probably changed it. The explanation would have made sense if it wasn't for the fact that every line that had been changed had a yellow or red line crossing it from the stop to tell riders that it wasn't available at the time. The thing about the 19 line was that there wasn't any red or yellow line crossing it out. It was completely gone and there was a blank spot where the 19 was written the day previous. No yellow or red line going across to show that it had been changed or removed. Completely blank spot. Due to this Mandela Effect we had to take another line only to get lost in another part of Krakow and almost missing our train. Thankfully we found another line connecting us to the same train station or more accurately close to it. This was the first blatant effect I had experienced. Thank you for reading.
