Okay here's mine. A bit different from some of the others posted so far. It honestly makes me believe in Bigfoot, or at least something similar.
I used to be a Scout, and me and my friend were were at scout camp one night. We decided to play a prank on a another troop that was camped about a mile away. If we got caught, we would have been kicked out, so we made a plan to complete our prank in complete darkness. We set our alarms for 2:30 in the morning and met under a tarp that was pitched in our campsite. The night was overcast, so there was no light from the moon, and we were shrouded in complete blackness.That's when the first incident happened. We both heard quick heavy footsteps like an adult running through the woods, saw a huge 8 foot tall shadow pass by us, then smash into the side of a latrine before running off into the woods. No light, no human words, and no apparent destination. Very creepy. Stupidly we decided to keep going. We made it about 200 yards outside our camp before the next incident happened. I heard the same footsteps behind me, and thinking it was a counselor on patrol I stopped and hid. Again there was no light, and this time the footsteps stopped behind me. I begin to move forward again, this time close to the water. I heard the footsteps parallel me in the water, hearing rapid splashing. I stopped again, and heard the chilling sound of water draining off something hairy and huge as it stopped and got out of the water. I heard the footsteps start rapidly coming towards me again, and that's when I broke. I ran back to my tent as fast as I could, tied it shut as tight as I could, and hid in the very bottom of my sleeping bag. Only time in my life that I have been truly scarred.
At first I thought it was a bear, but the footsteps were distinctly human, and walked with the exact same pace I had. Whether it was Bigfoot, or some spirit, it was chilling either way and made me a believer. And yes, my friend Javier had the exact same experience and we still talk about it to this day.
