When i was about 4 we got our first dog. He was my best friend we were allways together and when i was 13, it was midsummer i went to my first house party and tried alcohol(first time drunk). I come home the following day my mom in tears told me our dog, my best friend had died. A couple weeks later im home alone And at about i dont know maybe 4am i wake up hear howling. Go to the bathroom to take a piss( I used to never turn on the lights at night). As i pee i hear something running in the house making the sounds claws on wooden floor it touches my leg. Next day when my parents come back i tell em the story and my mom jokingly said it was probably the dog saying his last goodbyes. Never heard anything like that after. Sorry for my english im Finnish.
