It has happened a few times but generally always small and insignificant.
I went to school with a girl who went on to have 2 kids and we were FB friends. She lives in a different country to me and I never saw her or knew much about her. I was ttc at the time and getting to the stage where other women getting pregnant upset me a bit
One day I went to click on my Facebook icon and suddenly thought 'how will I feel if Old Friend has just had a third baby?' When I opened it up, there was a picture of Old Friend holding a baby with a birth announcement. I didn't even know she was pregnant.
Last year I dreamt all about a bracelet I used to have. I thought about it all day as the dream was very vivid. That evening I went to check the postbox at the bottom of our block of flats. There was a package for my husband. I was so surprised when he opened it, as inside was a man bracelet that my husband had bought for himself but never told me about.
Once I had a dream that a little boy in my class was actually cloned or had a twin. I remember looking at the one on the left and then the one on the right. I was very conscious of their position, left and right. The next day, the boys horrible father turned up at my classroom complaining that his son was writing with his left hand and I needed to correct this. Turns out he was very abusive and the mum and children did a runner to get away from him.
I had a dream where my brother, who was then 25 had a full head of white hair. I told my mum who said that my dad had made a comment the day before that my brother was so stressed 'that his hair would be turning white soon'.
I had the weirdest dream, full of symbolism and analogies that I wrote down after I had it on 31st September 2019. One day a few months later it suddenly struck it had been about the pandemic. The dream contained a scene were people had to stop going to places and doing activities and there was even a big city that I didn't recognise but I knew it was Asian, something like Hong Kong. Later realised it was Wuhan, that I'd never heard of before.
I've so many more.
