A/N: This one is really fucking short and also kind of terrible, but to be fair to myself I was on a bit of a deadline and I was writing it at stupid o'clock. The prompt for this was burnt toast and I'll explain my idea at the end because it's kind of weird.
Sam learned to know when a vision was about to hit. There was the most obvious clue of the splitting headache that always seemed to last far longer than was really necessary, but there were some more subtle signs too that he eventually began to pick up on. His vision would blur and his hearing seemed to become sharper. Sometimes he'd feel like they were being watched, or simply just a sense of dread. And then there was the strangest one: the smell of burnt toast.
The first time it happened, he and Jess had been getting ready for bed and she had stepped into the bathroom for a moment. His head had been pounding for a while but he put it down to the fact that he'd been pulling a few all-nighters that week to get a project done. At first he'd assumed that Jess had made some toast and left it for a little too long, but further inspection told him he was wrong. He'd asked her about it when she came back into the bedroom; she'd frowned before her eyes had blown wide and she started checking he wasn't having a stroke or something. He'd laughed it off and assured her he felt fine, but she still refused to sleep until he promised to go to the doctor's if it was still there in the morning.
That night he saw her burn on the ceiling for the first time.
It started happening more frequently and he learned not to say anything to avoid freaking them out too much. In truth, it freaked him out, but the John Winchester Academy had taught him how to hide everything beneath a mask of calm.
The smell was generally the first clue, first appearing about a minute before the vision. Not that it did any good; he couldn't control them and he never got used to how goddamn painful they were, especially when they progressed to daytime occurrences. He supposed it was nice if his freak powers to give him a little warning, but he could never quite appreciate it.
A/N: Okay, so a while back I read this book series called 'The Power of Five' and in it there were children with powers and psychic abilities and (if I remember right, it's been a few years since I've read them) at least one of the kids smells burnt toast before his powers manifest. And I thought this fit Sam quite well so I ran with it. Please leave a review if you have a moment. Bye!
