There are various types of etheric implants, but one classic example placed by reptilians starts at the nape, runs down the entire spine, and ends at the coccyx, the root chakra. This implant allows the reptilian to connect, acting as a transformer so the human does not feel the heavy energy of the reptilian. It enables the reptilian to feed on low vibrational energies like sexual energy, stress, anger, and hatred. The reptilian can manipulate the individual, implant thoughts, make them act in certain ways, and whisper suggestions into their mind.
