Not sure if I did this one upthread, as I have several. So ignore if I have done it. I may not have done it in its entireity. As it has a bit of a sting in the tail I don't always include when re-telling it.
As a kid, I had a couple of recurring dreams. One was about a flood, and being on some kind of wreckage, at the bottom of our old orchard. Under trees, anyway. Those were mahoosive trees there - so that's probably why I thought I was there. I couldn't swim, so it was really scary.
I also didn't think anything of it, as we lived near a river and I had grown up with my mother's stories of the flood that wiped out our family farm - whole dairy herd drowned, presumably uninsured as that lost us everything. Long before my time but still raw to my mum.
Anyway. When I was at uni, a world away, I woke up one night so terrified, I remember feeling round the walls of the room in the dark, panicking. I'd had another drowning dream. But this time, it was quite specific. I was in the sea, and close by the wreckage of a boat. It had gone down and there were people panicking in the water. Then I noticed near me, a middle aged man, very calm. It was like he was there but not there. I knew instantly that only I could see him. He said to me "Hold onto the wreckage. You'll be fine." or words to that effect. Even though I could now swim, I still hated being out of my depth. I was so panicked, I remember thinking if he hadn't said that, it wouldn't have occurred to me, obvious as it sounded. I grabbed summat and held on for dear life.
As the thing unfolded, I realised I was this time not in the river, as all my childhood dreams, but the sea. I could see xmas lights strung along the shore. And we were within sight of the shore, but quite a way out. The calm man moved away from me and was helping people, where he could yet I knew they couldn't see him, only I could. Then I woke up, searching for the light. Switched it on and I was crying and so upset it woke up the boyfriend. Now my husband.
So naturally I told him all the details of the dream, including that weird thing of xmas lights.
Next day I went to uni and thought no more of it. A new variant of my childhood dream.
Evening news - a disaster at sea. Quite a few people drowned. The TV showed... xmas lights along the shore. FFS.
My other half was watching too and he was as shocked as I was. I had the dream around 2am which was close to the time it was actually happening.
Many years later I got into genealogy. One thing led to another and I discovered one ancestor was a survivor of a boat being capsized on the river here. The same river in my dreams. He gave evidence at an inquest and so I was able to read his words. He was a steady, calm, middle aged man. Like the man in my dream. He only survived because someone on the riverbank shouted him to.... hold onto something, in the water.
