ok, as far as i know people have shadows right? right. however i was once walking along the street towards the air base here, when 4 small child size shadows ran past a hill at a very past pace. but there were no deaths here or anything like that. well another day when i was going to practice (capoeira) i saw it again right before i was about to do something, an i fell through the air the whole time hearing laughter but no one was around. ghost? demon? or coincidence i dont know but i do know something was there and it was not "coincidence"
