Fire Drill!!

I have been having such a hard time sleeping, went to bed about one am last night to be awakened by a screeching smoke alarm! It unnerved me to no end. I had to get a Nitro before I could even move. Kandi went crazy. She was trying to climb up my legs to get to me. My first thought was, the battery was bad, like the ones in the RV. They usually have a red re-set button, so I am trying to push a non existence button with a mop handle. Finally I heard people in the hall, so I opened the door to see what was going on. The people in the hall said we had to leave the building! Great, I am in my raggedy nightgown, so I put on shorts, shirt and shoes, got Kandi's leash. Then I thought well I might need my truck keys, and my purse, just in case I needed money. By the time I got out to the hall, trying to lock my door, the alarm stopped. No fire. False alarm. By the way, did I mention it was 4:00am? A bunch of old people, dressed in night clothes, half asleep is NOT a sight you might want to see! Gee.
Got back in, calmed Kandi down, took a Xanax, and tried to go back to sleep. It did make me consider, I need better plan to escape. I need to have my purse,glasses,keys and maybe a little bag with my meds by my bed, ready to go, just in case. The old lady that lives up on the second floor, and on a walker beat me down stairs! Should I have locked my door? Or, not lock, it would be a good time for thieves to loot the apartments? 
Something triggered the alarm in one of the apartments, and they all go off. I guess that is a good thing. It does give me second thoughts on living in an apartment complex that has eight buildings,three stories high. I am on the ground floor, right next to the breezeway to go outside. If we had been on fire, I would not have made it out! Scared the hell out of me!
