Strange Dream: Woken Up by an Alarm in a Dream.

I dreamt that my alarm clock had gone off. I woke up, in my dream and scratched a mosquito bite on my belly, and brooded.

Then I realized my alarm clock and bolted out of bed. I check the clock. It is 6pm. Weird!

This is as close to a nightmare as I have had in a while.

What does it mean?
