Andrew Gallimore
Andrew Gallimore is a British neurobiologist, pharmacologist, and author who argues that DMT (N,N-dimethyltryptamine) is a neuropharmacological key that grants access to parallel dimensions populated by alien intelligences. He is the author of Alien Information Theory: Psychedelic Drug Technologies and the Cosmic Game (2019), which presents a neuroscientific and information-theoretic framework for understanding DMT entities as real inhabitants of a non-ordinary reality.
DMT and Parallel Dimensions
Gallimore's central thesis is that the brain, under the influence of DMT, does not hallucinate but rather switches its tuning — perceiving a different but objectively real dimensional space. He draws on recent neuroimaging studies of DMT to argue that the brain activity patterns observed under the drug are inconsistent with a mere hallucination model and are better explained by access to a genuinely distinct information space.
DMT Entities
A central feature of the DMT experience reported by many users is encounter with autonomous, seemingly intelligent beings. Gallimore argues these entities communicate information and demonstrate volition that is inconsistent with the hypothesis that they are products of the user's own unconscious mind, and positions them as potential inhabitants of the same order of reality as extraterrestrial or non-human intelligences reported in other contexts.
Extended-State DMT
Gallimore has proposed and collaborated on research toward an "extended-state DMT" protocol using intravenous infusion to sustain the DMT experience for extended periods, enabling more systematic exploration of and communication with the dimensional space accessed by the molecule.

Consciousness researcher Andres Gomez Emilsson has endorsed Gallimore's neuropharmacological framework, describing him as someone who "really understands how the brain works" and whose argument that DMT instantly and radically alters the perceived reality — rather than merely distorting it — represents one of the most compelling common-sense cases for the objective existence of the dimensions accessed by the molecule. Emilsson has praised Gallimore's Reality Switch Technologies and noted having shared presentation stages with him at multiple events.
