Changes in felt gravity
Changes in felt gravity can be described as feeling that the pull of gravity has shifted in its direction, orientation, and speed. For example, during this state one may feel as if they are floating, moving, or accelerating forwards, backwards, upwards, downwards, or in an unspecifiable direction.
Changes in felt gravity are often accompanied by other coinciding effects such as geometry, internal hallucinations, and holes, spaces and voids. They are most commonly induced under the influence of heavy dosages of hallucinogenic compounds, such as psychedelics, dissociatives, cannabinoids, and salvinorin A. This holds particularly true during the rapid onset of DMT, with users commonly reporting an intense feeling of acceleration as they begin to come up on the substance.
