Predictive dreams or premonitions..I've had several, all of which came true.
I had a recurring dream that I was going blind.
I knew my son would marry someone who already had a wee boy, even though he absolutely insisted that if he ever did marry (he was a teenager at the time), he'd never contemplate bringing up someone else's child but 24 years later he's doing just that.
I also knew he'd have a daughter, long before he even had a serious partner. I was so sure that I made a quilt for her, bought books and toys and put them away for her arrival. She's 8 months old today.
Sadly I knew I'd find my mother dead but the strange thing about that was the event itself became a premonition.
Mum made nightly 'Goodnight-and-God Bless" phone calls to us and one night, didn't.
About 10:30 (quite later for her) I tried to phone her and it rang and rang.
I asked a friend to ring from a different phone. Same result.
I got my 12 year old son out of bed and we drove to Mums, letting ourselves in with our key.
Mum popped out of her room, 'What on earth are you two doing here at this time of night?"
I collapsed with tears of relief. She was just about to make the 'goodnight' call wheh we arrived.
After calming cups of tea, testing the phone which had no faults, my son and I returned home.
I knew even then, and told him, "this was a rehearsal", so when the same thing happened 4 weeks later, I knew Mum wouldn't be popping her head round the door in surprise.
My son too has very strong premonitions and usually acts on them but he once 'knew' his car was going to be stolen from the Mall carpark as he and friends were going into the complex to see a film.
He regretted not acting on that feeling as his car, his pride and joy, was taken and trashed in some distant area.
I've had a recurring dream about ringing 999 and in each dream there's a different reason why I never get through.
Twice in my real life I've needed to ring the emergency services and each time, though I got through, they didn't turn up. 
Now, a future happening and I have no strong feelings about this, just a very, very vivid dream.
I saw what looked like a car number plate - white rectangle with black lettering: "28th August 2021".
I haven't a clue what it means but I may buy a Lotto ticket (something I never do) just in case
