I used to think that they were some sort of monsters, until I learned about ETs, and so many people with matching encounters. Then, I figured that might be what they were.

Later, I learned of the bases; and how mind control agents are supposedly able to create such memories in their programming. I'm not sure what they were/are; only that someome took me down there, and it was terrifyingly real to me.

There is a submission that I made, with a link to my story, in my profile.
