Ghost story

My mother could find her way into an online shopping basket blindfolded but other types of internet navigation are difficult for her, due to her MS. It affects her co-ordination, her sight, and her thinking as well as giving her constant pain and frequent dizziness, so everything is a struggle.
I have ghostwritten the first chapter of her life story and entered it into a competition for her. As part of the competition rules she has to mark three other entries, which is easier said than done. She managed to read the first one and I entered the marks she suggested over the phone but after that finding the other two entries, even with my help, was beyond her so I marked them myself imitating her style, to a degree.

That was my good deed for the day or would have been if I hadn't been irritable with mum. The only other thing of note occurred just past midnight-i.e first thing this morning soon after I posted. I sent different messages to the ten women, almost all of which were based on something on their profile but I asked one if she'd ever seen a ghost. The dialogue continued:

Actually I have, and lots of ghostly experienced about 12 years ago

Why 12 years ago? Were you living somewhere haunted?

Yeah place had a weird feel to it

And how about the ghost you saw? You saw a ghost or heard/felt? Thanks for replying to me, BTW.

I was about 13/14 there were about 10 of us on the beach we all saw same thing. And np. Shame your in Kent otherwise I'd of said lets meet for a costa lol

It is a shame. I don't mean to impose on you but is there anything more you could tell me about the ghost you saw? Otherwise thank you anyway.

They're hard to explain about 8/10 of them sort of floating across the sand they were in long black cloaks with pointed hoods but like the pics/films I've seen the kkk wearing. Was really scary tbh

Intriguing. Was it at night? Where was this?

It was summer about 9ish I guess not quite dark
