Do you believe in ghosts?

i was reenacting the battle of gettysburg this summer and at 3 in the morning someone was standing in front of my tent. i thought, no big deal its just one of the officers checking on everyone;and i dozed off. i woke up 5 min. later and when i opened my eyes A SEE-THROUGH SHADOWISH FIGURE WAS INSIDE THE TENT LEANING OVER ME!! I jumped so high i almost broke the tent and pulled my bowie knife out. but then it just vanished into thin air. creepy or what? later on at the reenactment of appomatox i was igned night guard from 1 to 2 in the mornig. I GOT CHASED BY A GUY ON HORSE BACK WITH A SWORD!! yeah i had a rifle, but what the heck is a blank gonna do against him? i had my bayonet, but it was easier just to run than get that heavy thing out. the next day i asked about any pyschos riding around on horseback at night only to find out that we were the only unit there and we were all infantry. i also found out that in the battle a union horseman was shot by a north carolinian in the same spot the horseman first started chasing me at!super creepy!!
