The Hopi Indians refer to a race of reptillians called the Sheti or "Snake-Brothers" who live underground & above ground in shape shift "human" form. Reptillians have shown themselves to me as spirit attachments on many dealing w/ addictions. They're not kind. They've been here for YEARS. Depictions date back to Egyptians. In attachment form they can easily go from 3rd & 4th dimensions. They feed on & create fear, torture, evil, addiction, negativity, mental illness, human sacrifice, etc
