Weird dreams

I've been sleeping badly this week, due to exam stress, missing S, and large temperature variations between day and night. If I get overheated I get nightmares, and for the last few nights I've had a recurring theme in these nightmares. I dream that I wake up, overheated and gasping for breath (which indicates that I'm overheated when I'm dreaming lol). It's daytime, and later than it should be. I discover that the power is off, stumble out of bed and out into the living area, where I find that the rest of the family are out (as usual!) but they've left me asleep without letting me know that workmen were coming to do something electrical. So I stumble out in my pyjamas then get a massive shock when I find unexpected people in the house.

What the hell is my subconscious trying to tell me?!
