Other places with a bad vibe:
Scarborough and Robin Hood's Bay! Every part of this area felt off, even the sandy beaches on a sunny August day. I visited a few times, every trip we left early as I couldn't relax. The part with the old cable car lift, felt the worst.
Tried to do a ghost tour one year. We got the wrong start point so missed the tour, then got lost in the dark! Never again.
Lancaster Castle and the area surrounding it. Very bad vibes. Tried to go to the annual fireworks display twice, and couldn't make it through the evening. Even in a crowd!
Sheffield (every part). But especially the cave tours by boat! Never have I experienced fear like I did on that boat. Anyone else? You have to bend double in the boat to avoid banging your head on the ceiling!!
Barnsley: area between town and the hospital, near the Premier Inn. I used to walk very fast, head down, to get back home with my shopping. (15 years ago, student placement at the hospital!) The rest of Barnsley felt nice and safe. Local people assured me it was far from safe, but I only had bad vibes from one area.
Edinburgh always gave me bleak vibes, even on bright, dry days in summer.
Carlisle felt 'off' in places, mostly around the train station.
