Head Lights

I woke up late last night Startled by the light One on the wall to the left of me The other on the wall to the right I turned my head this way and that Which made it very clear The dawning light inside of my room Was coming from my ears My very first reaction Was one of lost control When I took my index fingers And plugged up my ear holes Which must have taken some effort That really wore me out As I inadvertently began to yawn The light came out my mouth The only answer to my question I must have had a bright idea But since I was sleeping at the time I can't remember what it is
