There are 2 (long) incidents that I know of which have been told to me by reliable, reasonable people I trust. I'll tell them both here since this is anon. I haven't even shared these with anyone else IRL, including DH, in case they laugh at me for believing any of this - since I'm totally unmystical, not religious, don't believe in ghosts, etc!!
1st:
Before I was born, my mum sadly lost a little girl close to term, happily followed by 3 boys with no complications (my brothers). She'd have been my oldest sister if she'd lived. After years of wanting a girl eventually my mum and dad had given up trying for another baby. My brothers grew up, and when they were young teenagers my mum took them to Blackpool for the day (my dad was at work I assume).
My mum has only ever spoken about this once, because she's a complete no-nonsense type, and I'm 100% sure she wouldn't lie to me about what happened.
But apparently as my brothers went off to buy some sweets at a stand, and my mum was watching them, a old-ish woman came up to my mum. She said that she didn't want to upset my mum but that she had a message to give her: the little girl that was lost before mum's 3 boys was not the only girl mum was supposed to have, and that this time next year another girl would arrive, followed the year after with another girl. She told my mum not to be upset and that the two sisters would get on in the way my mum never had with her own sister. When my mum asked her who she was, the lady said that she just had a gift for sensing these things and had waited until my brothers were out of earshot before saying something in case she upset her. The lady wished her well and said her goodbyes.
I arrived 1 year to the day that my mum went in Blackpool (although at night - I was born about 30 mins to midnight). My youngest sister arrived 13 months after me.
I have no reason to doubt my mum's story, and the one time she did speak about it, I did ask my brothers (seperately) about "the day trip to Blackpool" - although one of them couldn't remember anything about a sweet stand, my oldest two brothers do remember a candy floss stand and getting sweets there that day.
I'm not sure what to make of all that.
2nd:
When I was at university, I lived with 2 other girls, and I've kept in contact many many years later with one of them. We don't catch up very often, but I do remember a story she told me about our flat about 10 years after we moved out and went our seperate ways.
Again, she is a very solid, reliable person and was doing biology at uni. At the time, she had a boyfriend in the same year as us who was studying music - he had his own flat share a bit further from campus but they often used to visit live music bars/drinks promo nights and crash at our place for a few hours until lectures the next morning.
The incident she told me about, and doesn't like talking about even now, is that one morning they were walking down the road from a late night sesh at about 5am in the morning. She maintains that neither of them were anywhere close to drunk the entire evening, although they had been drinking earlier in the night, and she never touched drugs as far as i was aware (then and now).
As they rounded the corner to the house we were sharing, it was dawn - streetlights still on, but getting lighter. Rounding the bend, as they got to next door's gate, my friend noticed something at the other end of the street underneath a streetlamp. It was a figure walking AWAY from them with great big lopes, massive strides, just strolling. Apparently it looked very, very tall and very very thin - cartoon proportions, almost half the height of the lamp post. But no "detail" apparently - she tried to explain it and from what I could gather it was like an outline of a person, there was just blackness where the face, body, clothes, should have been - like an outline, or a shadow. Or a straw man with a circle where the head should have been. But much too thin and tall to be a straw scarecrow.
My friend stopped dead in her tracks, and her boyfriend noticed, asked her what's wrong, and looked to where she was looking.
He stared at it too. According to Ellie (my friend) the thing appeared to pause in its strolling and turn to the side to look around at them - the overwhelming sense of emotion that came from it was a rush of malice. She said it was like a wave of negative emotion came from it. For some reason she said that she seemed to feel as if it was ANGRY about something - that it had been spotted?
It turned a bit more and started coming towards them, and although it was at the other end of the road, it could cover the distance much faster than a normal human because it was so tall and long.
At this, my friend's BF apparently grabbed her hand, ran into our garden, and they frantically started trying to get the keys from her bag. They got inside before it reached our house, but when they looked back at the door after locking it behind them, the 2 panels of misty glass that covered the top half of our door had a shadow twig type figure, like it was looking for them in there. Apparently it stayed there for 15 or 20 seconds, peering in, whilst they cowered in the stairwell holding their breath.
She said she'll never forget the unhuman shape and thinness of the thing, and its stick arms as it peered in the glass. And the malice / feeling that it was very very angry at them for seeing it.
Paranoia of student drunks with too little sleep? Normally I'd laugh and say without a doubt, but I know my friend, and she maintains that she'd barely drunk that night, her and her boyfriend saw the same thing, later collaborated, and she was so freaked out by it that she never came home alone at dawn EVER again (I do remember her doing this, but I thought it had to do with knuckling down for exams!!, looking back).
