sirens

I hear sirens.. fire trucks being sent out to another grass fire.. it's been crazy the past two days.. my hubby has been out on one for a long time and must be so tired and hungry. The scanner has gotten quiet finally.. I know I should go to bed, I have to get up in a few hours for school.. but how can I sleep with all those sirens going off? Suddenly I realize that the sirens I'm hearing aren't there at all, they're only in my head. I wish knowing that would make them stop. I close my eyes and and try to push them away searching for the silence I should hear in the quiet of the night. I pray the Lord's protection over the firefighters & peace for their families.. a restful sleep to all. Amen & Goodnight.
