When I was seven, I had a premonition my school would burn down. A really vivid dream that it did. Then, then next week IT DID BURN DOWN. Some builders were doing work on the roof, they spilled some tar, and it went up while we were in the assembly.
OMG OMG OMG!
I'm totally, like, psychic.
Only I'm not. It's a really normal dream for kids to have. I bet every kid thinks wistfully about their school burning own and having another 6 weeks of holiday - hooray hooray, and all the parents groan and mutter that they will need more gin to cope.
Plus, a horrible boy kept telling me he was going to burn the school down while I was having a wee, and being at just the age when I was convinced that I was absolutely certainly a minature Sherlock Holmes, I spent my time trying to catch him in the act of doing nefarious and subtle things like playing with matches. I also accused the school caretaker of mass murder, fortunately he was a man with a good sense of humour.
In the same way, we all dread parents or friends becoming sick and think about it often - perhaps fleetingly, perhaps consciously. I must think about losing my parents a good number of times a day - it's a real fear for me, especially since they both had cancer. These feelings are a coincidence.
