One day my friend and I were biking on bike trails deep in the woods. It was around 4:00pm but we didn’t know the exact time. For an hour we biked around until about 5:00pm. It was getting dark and we had no idea where we were. I was following my friend and he said “follow me” but I looked down for a second. When I looked back up he was gone. In Front of me layed 2 trails, 1 curved left, the other curved right. I was very confused but went down the trail to the right. A little down the trail I noticed a dim glow in the distance passed the trees, however; it was off the bike trail deep in the woods. Curious I biked over to it, it was a house. Old and rundown laid this house however the lights were on, someone had to be home. I slowly started walking up to the house to look in the windows. When I looked in the first window it was an empty living room with no form of life. At the second window I noticed a guy. This guy was in a lab suit and I saw him throw a long garbage bag down the stairs. I also noticed his hands were all red and so was the knife on the counter next to him. I instantly sprinted away and from that day don’t know what happened.
