Voices in the fan

So, the other night I was sitting in my new apartment by myself and I began hearing my sister talking into her cell phone. No big deal, but I could barely hear her over the AC fan. I called out to her 2 or 3 times, but figured she was just waiting to finish up her phone call.

After about 5 minutes I began to hear the person she was talking also. But the words weren't audible. Still, nothing registered on my mind as wrong.

I was in the middle of a good writing session, which means a do not disturb sign on my bedroom, but after 10 minutes I began to dwell on how long she had been talking without at least knocking on the door or yelling out hello.

Deciding to hear what she was saying, I reached over and switched off the AC Vent...Nothing. No noise, no conversation, no footsteps.

I walked around the apartment, but of course no one but my dog, Zavi was there. And she had been napping at my feet the whole time.

So what happened, did my imagination get away from me? Did my mind make up the noises? What was going on I asked myself, am I nuts. I mean, I feel pretty far from schizophrenic, but real crazy people don't know they're crazy.

Sitting back down I laughed it off. Had to be imagining things. Right?

"Right." answered the voice in the fan.
