I love Royal Victoria Country Park and have camped there so have been there at night too but I totally agree it has a 'feeling' to it. It is beautiful but always feels as if there is something else going on that we can't see.
Hungerford - went there a couple of years after the awful shooting - I felt like we were intruding. The locals were welcoming but I didn't feel right being there.
Thatched B and B in Charmouth - stayed there about 30 years ago with exH (he doesn't get the honour of being exDH). Very old, beautiful, quaint cottage but full of dark wood and panelling and heavy doors. No ensuite. Was completely petrified the whole time and couldn't sleep, felt if I did something would 'get me'. Couldn't bring myself to go to the loo in the night even though I was bursting. worse place I have ever slept (or not slept).
Glasto - agree it is an odd place and does attract some damaged individuals. I used to like to go there and enjoyed the cafes and slow pace but went 2 years ago and was really disappointed, the town had lost it's good vibe and felt tense and touristy. The Tor, which used to feel quite spiritual, was heaving and full of people being t**ts - including a naked woman and her vicious dog!
Agree re Salisbury - always feels odd and slightly out of kilter and also Arundel Castle - there is a room there with a arched window (probably lots to be honest) but one particular one made me feel uncomfortable - exH took a photo of me sat by it and I feel uncomfortable looking at the picture still - it's as if I am back there - I have the same feeling.
Local to me is George Staunton Country Park - have always felt a strange deja vu there and an odd feeling of sadness and, to an extent an incongruous anger, that the house that was there has been knocked down (in the 1960s I think). I feel connected to it but I have no idea why. I have asked my parents if we went there when I was little and we did but nothing special or odd happened.
I am not a 'woo' kind of person yet, like others, I seem to be aware of the differences some places have.
