Simply a wake up call

Date: 4/14/2016

It was a simple dream. The phone rang, I picked it up saying "hello", "good morning" a voice responded. The voice was that of a girl, younger, but not a child, in fact she sounded like she was of another world, and as soon as she said 'good morning' I became confused, because I knew I couldn't respond, I knew I couldn't say anything else to her, the conversation was over. She was just there to remind me to wake up... The night before I closed the single curtain in my room so no light could get through to wake me up and I specifically didn't set an alarm, so the only way for me to wake up would be from myself, not sunlight or an alarm. I remembered this in my dream and woke up, 6 hours of sleep.
