I have felt it in a few places.
One is a the area at the bottom of the lane my grandparents' house was on when I was a child. I used to spend every 6 week summer holiday at their house and I was terrified of that area of the lane. At the time, you used to go down the lane and sort of shimmy down a sandy cliff to get to the beach there (the landowner has since closed the fields off so access ends at the bottom of the lane these days) so I would be made to walk through it daily on our way to the beach and would have to close my eyes and run as fast as I could to get into the fields on the other side. As soon as I was past the end of the lane I was absolutely fine, but would have to do the same in reverse on the way home.
Years later my df built his own house on the site of my gp's and my family and I regularly travel over for holidays. I still can't go down there. Dh regularly walks the dogs down there and the dcs often go with him. None of them are remotely bothered by it, but I can feel an overwhelming, almost suffocating sense of evil as soon as I start walking in that direction, that just grows and intensifies as I approach the area. I found out fairly recently that, historically, there was one particularly bad sea disaster close by and the bodies of the dead were brought ashore and laid out at that point before being taken on their final journey.
There was also a small cottage local to the house that used the front room as a shop, selling basics, sweets and cigarettes to the locals, as the nearest town was an hour's bus ride away. Something about the place terrified me, but as the youngest out of my sister and a large group of cousins, I was always laughed at and made to go with them anyway. I would literally shake and start to feel like I was going to be sick as I approached the doorway and once inside felt like I was going to suffocate. The family moved on and sold it years ago and it's now been renovated and is rented out as a holiday home, but I still can't walk the place.
The other, strong feeling I've had was at Keele University. Dh, myself and dh's best friend decided to cross the fields at the back of his halls of residence as a short cut to the bar under Keele Hall. It was night, but a very clear light with strong moonlight that made it easy to see quite a long way. We rounded the corner into the field, which ran alongside a very high stone wall and all three of us stopped dead, looked at each other with eyes like dinner plates and ran as fast as we could back the way we'd come. You don't get many people less woo than dh and his friend was an extremely unshakeable, very strong guy (all long hair, biker gear and heavy rock music). Not one of us could explain what it was, it was just an overwhelming sense of evil that kind of permeated the air and provoked instant panic and need to escape. We'd walked that field before with no issue whatsoever, but after that not one of us ever did again, preferring the longer walk through the campus than risking ever experiencing that again.
As for people. I've met quite a few that have given be a bad vibe and I've later been proven right about, but only two that really gave me a sense of evil. One was one of our primary school teachers. He was young and attractive and everybody seemed to love him, but I couldn't stand being in the same room as him and even seeing him across the playground would make me shudder. He'd only been there a year or so when he suddenly disappeared without warning - he was convicted of abusing the sibling of one of my classmates after setting up a complicated ruse to get them on their own. 
The second was one of my secondary school teachers. Strangely enough he lived in the village I grew up in. I didn't know him at all, but he lived a few streets away and I'd seen him around. I only needed to catch a glimpse of him to get an instant wave of nausea and a feeling of panic and needing to run. I was horrified when we moved house, I started secondary and he turned out to be one of my teachers. I completely flunked his subject, because I was so terrified of him, I spent the whole year feeling sick during his lessons and hiding at the back of the class unable to think. He'd never done anything to deserve my reaction to him, it was far more gut/visceral than logical.
I was speaking to my dh about secondary school the other day (dh went to the same school, but was a couple of years below me and we didn't know each other at the time). He was going through various teachers and their foibles etc, then he mentioned this particular teacher and before I said anything myself, described having very similar feelings to me about him. He also said a lot of his friends felt the same (whereas I'd never confided in anyone about it, so I don't know if any of my friends felt the same). As far as I know he's never been in trouble or convicted of anything, so I have no idea if my feelings were justified, although dh said he witnessed him fly into a rage and threaten a pupil with a tool from the woodworking room, so who knows?
