A short but informative book is about the Dulce Base, and the many human prisoners there.

Note: The Earth is definitely Flat & aliens/UFOs are definitely Real. If you are not fully awake to both of these Truths, then you are not yet CONSCIOUS. What real Truthers now are doing is digging into the connecting dots. Are the ETs all inter-dimensional beings and/or is the earth located on an infinite plane with many more worlds out past the ice walls? Don't be a half awake flat earther that thinks ETs/UFOs are not real, and don't be a half awake ufologist that thinks we live on a spinning ball hurling through outer space. Time to FULLY WAKE UP people & stop fighting each other!!!

"The 5 rules to AWAKENING: Rule #1 - Everything you were ever taught is a lie by design; Rule #2 - governments lie 100% of the time, they always have, and they always will; Rule #3 - the Illuminati controlled mainstream media is not reality, but rather is lies, disinformation, half-truths, & fake events carried out by gov/media hired crisis actors (aka role players); Rule #4 - Spirituality & Reincarnation are reality, whereas religions are simply government crowd control measures; and Rule #5 - this plane(t) called earth is a flat, motionless plane, it is not a spinning ball hurling through outer space. Furthermore, the 4 Sources of Disinformation that are ALWAYS FAKE: government, mainstream media news, matrix sciences, & religions." -- Sergeant Major
