During the years I spent in the DUMB's a Zeta Reticulan would show me stasis tubes - the message being "Quit working the child abduction cases or YOU will end up in one of these tubes!"

​

The stasis tubes I saw were deep underground. I was standing on a metal grate walkway so could see level upon level of these tubes. On the level I was on, they stretched as far as the eye could see.

​

Live human beings were inside these tubes filled with an aqua colored liquid or a violet colored gas. Many of them were missing body parts the deep black military had used for cloning purposes. The tube closest to me contained a little brown-haired boy maybe 9 or 10 years old missing his left eye and arm.

​

The DUMB's also contain cryo tubes containing alien/human hybrids.
