​Black hole have developed a taste for human flesh. They don’t get it very often as humans take many millenia to develop the proper technology needed to travel the stars on their own. Instead, they must rely on their thought-forms to travel to the small blue planet the humans called home and bring the tasty morsels to the waiting abyss of their masters.

The thought-forms were on a higher vibrational frequency that humans were, four and five dimensional creatures that they were, so they had to slow themselves down to the operational frequency of organic life, a much more difficult task than one might imagine. Because of this, some humans escaped. 
Those lucky humans termed the incidents “alien abductions,” but they were wrong.
There were no aliens in the vastness of space.
There were only humans and the hungry mouths that fed on them
