Most of my dreams, when I remember them, are very vivid, very realistic and very emotionally-intense. I've written some of them down before now, normally the weirdest or most upsetting, to try and have people interpret them. I've never figured out what sets them off though, because most of the time I don't remember dreaming at all.

I don't think the dreams I have are lucid dreams, because I'm not aware that they're dreams, and I can't control what's happening in them. Sometimes they tie into reality too - I've had a few where I've set an alarm off in the dream and then woken up to find my alarm is really going off. I don't think that it's the real world alarm that happens first though - in my dreams I normally have a bit of a build up to the alarm going off, for example I'm climbling something and I know if I fall I'll trip the sensors... and then I do fall.

So, sorry, no ideas why it's happening, but if you figure it out let me know!
