I don't know if "spooked" is the right word for my experience at the Alamo, but it is one of several places I have been where I had an episode of what felt like being frozen in time. My immediate surroundings sort of faded away like into the distance and for a few moments it was like I was there and feeling all the energy around me of events that had taken place there. It was more like stepping into a time warp. Gives me chills, even now, talking about it.
Two other such places were St. Simon's Island in Georgia, actually, in two locations there....the graveyard at the church and Fort Frederica. But the most intensely that I have experienced that was at Pecos Pueblo, in New Mexico, so much so, that I was drawn to return on subsequent occasions.
It has happened to me twice in my life, and the first time was at Fort Frederica, when I was only 6 years old. I have a very vague memory of it now, but I dreamt about it for years afterward - not nightmares, by any means, but odd dreams of being someone else.
The second time was at Devil's Den at Gettysburg. An overwhelming smell of blood and honeysuckle blossoms...my nephew and I both smelled it, and he almost blacked out. I came close to fainting myself. My husband and my son didn't smell a thing.
Wow! I wasn't expecting to see my hometown mentioned when I was reading this thread -- I was born and raised on St. Simons Island. I know there are lots of ghost stories about the Christ Church cemetery, and even the lighthouse, although I'd never heard ghost stories at Fort Frederica.
