Just took a little nap and had a weird dream.

I was at a conference, and near the dream's end, I was wandering through the centre's gigantic and crowded gift shop.

Suddenly, I heard a friend's voice calling me, but in the crowd, I didn't see him. He kept calling, and I was extremely irritated as the sound didn't change as I turned my head from here to there.

I was wandering, whether I had gone deaf on one ear. Eventually, I gave up and decided to go to my room.

Obviously, what happened,

made total sense: In a dream, all sound originates in my own head, and thus, has no direction.

Still: I find it strange that something like that could interfere with the dream's events.

@mina You can have such "interferings" especially in periods before waking up or sleeping less deep.
Examples: In your dream something starts to annoy you, or you try to find something strange ... later wake up and notice that you have to pee. Your brain annoyed you deliberately to wake you up just in time.
Or you dream that s'o shouts at you, wake up and notice that you slept in front of the TV.
