Fire alarm signal in the middle of the night

I just lay down and after about 15 minutes, a very loud voice suddenly started speaking in Georgian. At first, I didn't understand what it was and thought that maybe someone had opened the door. So I immediately jumped out of bed and came to the door, but the door was closed and nobody had opened it. And then I realized that it was the speakers announcing a fire emergency, which meant that I needed to leave the apartment. I only understood what was happening when the voice started saying it in English.

So it was a bit of a shock to me because in the middle of the night they were telling me that I should leave the apartment immediately. I didn't have many options, so I just put my documents, money and laptop into my backpack and went to the corridor. But the corridor was completely empty. I met only one woman from Belarus. She also didn't understand what had happened and asked me about it. But I still couldn't tell her anything because I didn't know what was happening either.

After that, I just walked around the corridor, checked that the elevators were working and looked outside through the windows. Luckily, everything outside was quite calm and I didn't notice anybody there. So I decided to come back to my apartment and check the other side of the building from my balcony. Everything was quiet there too. I didn't see any crowds, fire trucks or anything else unusual. By then I was already a bit calmer about staying in the building instead of going down the stairs from the 28th floor to the first floor.

With this crazy story, I didn't sleep for about 30 minutes because I wanted to be sure that everything it wouldn't happen again. So I looked from my balcony and listened to the elevator working and people coming and leaving. I just wanted to make sure that everything was okay so I wouldn't have to jump out of bed again and could sleep calmly without any worries.
