Scare of the night

So last night I got up at 3:15 to go to the bathroom, and I decided to scoot down in my underwear..lol...so i went to the bathroom and took to aspirin cause i had a growing pain...i walked slowly up the stairs listening to make sure no on was coming out of my parent's room, so i got on the landing and got right near my bedroom door and i ran face first into something...I screamed so loud..and burst into tears cause I had no idea what I ran into...needless to say, my dad freaked out on my for running into him...he started yelling at me to open my eyes (which is really hard to do when you're half asleep, it's pitch black and you can't see without your glasses)
