Signifiers?

So it seems I had a really strange dream last night. And I'm not sure what it had to do with my current state of mind, for I remember going to bed at 12 last night thinking about my media kit. Wait, or was it about moral panics? Argh, can't remember...

Anyway, the point is my dream - it was so strange. It was somewhat a reminiscence of my secondary school days but the sequence of everything was jumbled up - I was a student (yes, complete with my awfully green school uniform...yikes!) and I was along the corridor along the school hall (it was the SKSS school hall....!!!) and was looking out to the school gate as if I was waiting for someone or something. Suddenly, my best friend (it was TBF but in the image of a really good friend from school back then...???) attacked me from behind. Hmmm...how do I describe the attack which felt so real? It was as if we were in a rugby match and you know the way the guys tackle at mid-field to get the ball? Yea, it was like that. And the result of that attack? I ended up with a broken leg.

Then, I jolted awake and wondered, "Whoa, what was that?"

And now, though it's been six hours, I'm still wondering about the dream: What did it signify? Or was it simply my body's way of telling me I've been too tensed up?

Hmmm...what exactly is it?
