There's a creatures outside

Chapter 1

I woke up to an emergency alert at 6 a.m. this morning on my phone. Checking my phone,the alert read"Go indoors immediately and remain inside. Await further instruction". After living here for 10 years I've only ever received a handful of emergency alerts which all presented themselves as test for the emergency alert system. Generally,I live my life pretty freely and don't take life too seriously. Unfortunately for me,this mean I'm not the type of person who prepares for the worst to happen which im now realise is what i should have been doing.

  I thought to myself "better safe than sorry"so after getting out of bed,i immediately headed downstairs and checked that both the front and back doors were locked and deadbolted. I live alone and always lock my doors at night,but I needed to verify this simply for sanity's sake, even if i didn't know exactly what was going on. I live in a decently sized two-story house that I've worked my ass off to make a reality, the windows downstairs all have solid security screens on them meaning there was no need for me to check the locks on those. After securing the house I went back  upstairs to my bedroom and tried to make a couple of calls. Initially i called my boss, I couldn't just expect to get the day off work without explaining the situation, if there even was a situation. The phone rang for some time before directing me to her voicemail system. I left a message explaining the emergency alert I received and told her to call me back when she gets the chance so we can discuss what's happened. I tried calling my parent but was again sent straight to their voicemail system. I think at this point was when I was starting to get worried. My parent live almost 2 hours away from me and were always awake at the ass crack of dawn, they never left the house before 8 a.m. but I still tried to convince myself they were busy with something else. So again I left a message for them to get back to me when they could.

    My phone dinged. A message from one of my work colleagues,kou. He was asking whether I had received the emergency alert too and if i knew anything about why it was sent out. I replied immediately and told him I didn't know anymore than he did but I'd let him know if i found anything out. I needed to calm down now,there was no use worrying over something yet that I didn't even know about. I decided to shower first before having a quick breakfast and  turning on the television to get my mind of whatever could be going on.

   At this point,it was about 7:30 a.m., the time i would usually be leaving for work. I'm not one to purposely ignore warning sign so I'd rather get an angry text from my boss than get caught up in whatever caused the emergency alert to be sent in the first place. When I turned the television on,the same emergency alert sound invade my ears. The volume was so high from the music I was listening to last night I had to dive for the remote to turn it down. The same words that my phone woke me up to were the only words on the screen."Go indoors immediately and remain inside. Await further instruction".
Now I was extremely worried. I was realising this couldn't just be an accident or a test. I'd never seen an emergency warning like this, let alone it being presented on every channel i flicked through. Without any additional information, there was no way for me to know what was going on or how to prepare for it. After turning the volume from the television all the way down, to get a break from that blaring alert sound. I realised how quiet it was outside. No cars commuting, bird chirping, neighbours chatting, or airplane flying over head, nothing. I never realised how accustomed I had become to this background sound. This lack of  background sound make me feel incredibly uneasy like I could sense something was wrong regardless of the emergency alerts.
