2 spring to mind, one that I can now logically explain (but for years was convinced was a premonition)
First though, my Granddad died 3 years before my DD was born. It was my first experience of loss and along with the rest of the family, I was understandably devastated. He was a funny man who taught Biggles to fly and Nat King Cole to sing allegedly
So, DD was born, I was an ELCS and it was Christmas. My mum (birthing partner) had asked that I wear Granddad's wedding ring to theatre, so that he could be part of it. Naturally I agreed.
During the operation the staff had a Christmas CD playing (not at my request) and as DD was born I noticed the song that was playing. The Christmas Song by.....Nat King Cole.
We took it as a sign that he was with us 
My other story/premonition. I once had a dream that I was stood on an American style veranda, watching planes take off from Stansted airport. I was looking out across farmer's fields.
As I watched, a 747 jumbo jet took off. It lifted in the air before plummeting to the ground. I can still feel the panic and hopelessness, utter terror, I was hysterical. A voice behind me said "don't worry it's just a cargo plane" (in my dream I took that to mean it could have been worse, casualty wise)
The dream was so vivid that I phoned my mum and relayed it to her .
A few weeks later, as I walked across a petrol forecourt I saw the newspaper headlines - a cargo plane had crashed just after take off from Stansted. I froze to the spot!
For years I've retold this story and people have had that look that says "I'm pretending to believe you but we both know it's bullshit"
More recently, with an older and wiser head I've realised that:
I worked in the aviation industry, flew all over the world regularly. Therefore I would subconsciously be thinking about the possibility of a plane crash.
Although I hadn't been to Stansted, I worked out of Gatwick and my colleague had worked at Stansted for years and was always regaling me with stories of her time there.
I'd previously been based at Cambridge, on a business park next to the airport. For those not local, the airport is very small and when a plane takes off the main road running alongside is closed (kind of like a level crossing).
A lady I worked with was always telling me how amazing it was this one time a 747 had landed there. In order to get it back in the air the engineers had to strip alsorts of nonessential equipment out, to lighten it so that it could take off on the short runway.
So put all that together and you've got a dream that picked various conversations and memories out of my vaults, coincidentally follows an actual plane crash.
I'm not psychic after all
