Sound.

A nightmare early this morning woke me up. I got out of bed to walk it off and came to a stop in the hallway. I looked towards the windows, and paused. Everything was so quiet. I started to fear that everything I dreamed about had come true. I went back to bed and sobbed. Then the cat who never comes to bed, came to bed and cooed to me. I was convinced that it had all happened. I knew somewhere in my heart that we lost him. I eventually reasoned with myself to drift back to sleep and a phone call this morning confirmed that everyone was safe.

I've really frightened myself. This is the second time this week that I felt something terrible was going to happen to someone I loved.
