I saw a ghost when I was staying at Dartington Hall in Devon in the 1960s. I think there are many different kinds of entities, some are scary and some aren't, it depends on the state of mind you're in when you are confronted. I found that quite scary because it appeared when I was asleep, so it was quite a shock, but the other ones I've encountered, I didn't find scary. I have a lot more understanding of them.
