I like getting woken up in such a way that before I open my eyes, the sound that is to wake me up becomes a part of my dream.
I had an interesting experience this morning, wherein I had set my alarm on my computer but had forgotten to turn the volume up loud. When the alarm came on it was a pretty quiet noise, but enough for me to hear it.
While still in a dream, I heard this noise in the background, and started to become annoyed by it. I spent the rest of my slumber searching my dream for the sound in order to silence this irritating noise.
I woke up five minutes after my alarm had started making this noise and immediately slapped my hand to my face in grief.
