I have had a couple of dreams where something has happened in the dream, only for it to happen soon after.
The first is a geeky one, I dreamt of a green Class 60 (a type of freight loco), and a few days later I went to the Old Oak Common Depot open day in west London, and what did they have? Yes, 60081 in GWR green ('60s have never carried green at any time in their careers, this is the only time its happened), a very special repaint, done in secret especially for the event, we were all supposed to be surprised, and people were.... Except for me... Who was trying to remember where he'd seen it before!
Coincidence?? Maybe, and I know it doesn't sound like much to the average person but it seemed a bit strange that I'd dream of something so random and utterly specific.
Anyway, the other was when I was at College and they had some old and rather dodgy lifts. I dreamt that I was in one when it suddenly plummeted to the ground. It seemed so real, I was scared! I woke up just before impact.
A few days later, one of the same lifts 'slipped' for want of a better word, falling 3 or 4 floors before the safety brakes came on, injuring several people inside.
I had had a similar dream about lifts before involving my Mum, so I NEVER used any of those or any other lifts again, and even now I generally avoid lifts when I can!
