Before you go any further I feel I must admit that you may not gain any real useful tips here. I mean the tips you are about to read are given to you by a fully grown adult who spent the most part of last night curled up in a ball with one finger over the call button and 999 ready dialed in. Which brings me to my first tip
If you find yourself loosing grip with sanity through fear you may find some comfort, whilst curled up in a ball, dialing 999 into your phone’s keypad and a finger ready over the call button whilst keeping one eye on the door for intruders.
Search the house for anything suitable to use as a weapon and store it next to your bed. If you find yourself too terrified at this point to go down stairs these ‘weapons’ could include a hairbrush, hairspray, the remote control and a nerf gun (they hurt real bad if thrown at ones head, I’ve had one thrown at my head by an over excited toddler).
Hiding under the covers. It’s the obvious one but effective. We’ve all learnt from hide and seek if you can’t see someone (an intruder for example) then surely they can’t see you.
It’s always good to be prepared for an alien invasion. As a scaredy cat you will be sure this will happen when you are home alone. Prepare the weapons and maybe even set up a camera, if you survive the alien probing you could cash in on the video!
