The ankle biters have been sustaining their control with a special technology that is called The Veil. It is an electromagnetic frequency fence on the lower astral and especially on the etheric plane, extending maximally 8.6 miles upwards and downwards from the surface ground level of our planet, that to a great extent prevents the Light from coming into the quarantine Earth. The Veil is being operated by the non-physical ankle biters. This technology could be best described as etheric HAARP. This technology distorts the time / space structure on quantum level and thus creates big difficulties for UFO propulsion systems of the positive ET forces. In the past, this has hindered the progress of the positive ET races towards this planet significantly.
Apart from keeping the good ETs at bay, the Veil has a function of programming / reprogramming the human population and keeping it in the reincarnation / recycling process. Few of the main astral / etheric programs for incarnated humans currently in operation are:
-Lowering of consciousness and light body / merkaba deactivation. This program is maintained with etheric standing wave resonance technology.
-Blocking of free will and of positive initiative. This program is maintained with etheric infrasound technology. Part of that sound precipitates towards the physical plane and some people can hear it as a very low frequency hum. This was the source of mysterious sounds that people heard in the beginning of 2012 and not the destruction of deep underground military bases, as some sources erroneously reported.

Don't worry, this stuff is not directly harmful, just extremely annoying.
