When I was nine or ten, my family and I took a ferry to Port Townsend; we walked along the beach and eventually began to explore the town. One of the first places we came to was a courthouse and jail turned museum, a single lady running it. I remember it being empty except for us and the lady.
The first floor is the courtroom, go down a staircase and that lead to the jail cells downstairs. We looked around for a short while and then decided to go downstairs, as you are going down the stairs, the cells slowly come into your view, poised inside the cells were life like dummies positioned in various poses, if you don't expect to see them there you're going to be startled. Once we reached the cells, my mom saw two evil looking sprits inside the cells, one of them was an old lady shackled to the wall, with long shaggily hair, staring at her with an evil expression, a terror able grin with no teeth. The second was a man; she said "he was nasty looking". My mom later told me she wanted to bolt up the stairs right then.
My experience there was a lot tamer, my dad walked into the cells, to see what it was like. When he wanted me to come in, as I tried to walk towards the cells, it was like there was an invisible shield around the cells and it was preventing me being too close to them, at least that's what it felt like. Needless to say, we went to that museum again.
The lady in charge never mentioned any ghosts, either she never went downstairs, or if she did know, kept it a secret. We come didn't across any other ghosts in Port Townsend that I can recall. Thank you for reading.
