Graham Nicholls, born in 1975, is a British author, installation artist, and expert on out-of-body experiences (OBEs). He has lectured on parapsychology, ethics, and art at various institutions. Nicholls's early life in a challenging environment was shaped by literature, art, science, and spiritual philosophies, which he credits with helping him transcend his circumstances.

His artistic career, beginning in the early 1990s, focuses on themes like sensory deprivation, hypnosis, and psi abilities. A notable work is "The Living Image," an interactive virtual reality installation created in collaboration with others for London's Science Museum, which drew upon his personal experiences and childhood locations. This project was the subject of academic study. Nicholls claims to have experienced OBEs since childhood, leading him to explore parapsychology and the potential acceptance of psi by mainstream science. He has engaged in telepathy experiments with Rupert Sheldrake and claims to have had verifiable OBEs, documented with witness accounts. However, his work has faced skepticism regarding its scientific rigor.

Graham Nicholls's artistic endeavors since the early 1990s delve into profound psychological and esoteric themes, including sensory deprivation, hypnosis, and psi phenomena. His artistic output often integrates technology and science, exemplified by "The Living Image," an interactive virtual reality installation developed for London's Science Museum. This project, a collaboration with 3D designer Roma Patel and artist Trudi Entwistle, was deeply rooted in Nicholls's personal life and childhood environments. The installation's exploration of virtual reality and its impact was later examined in academic research. Nicholls's digital art projects have gained international recognition, noted in the "Handbook of the economics of art and culture."

Nicholls has reported experiencing out-of-body experiences (OBEs) since approximately age twelve, which spurred his deep investigation into parapsychology. He posits that mainstream science will eventually recognize psi, or psychical perceptions, as natural phenomena. In 2009, he initiated telepathy experiments in collaboration with scientist Rupert Sheldrake, contributing data to Sheldrake's research. Nicholls also claims to have documented veridical OBEs, presenting evidence in his books, articles, and videos where witnesses corroborate his accounts. These claims, particularly the notion of objective OBEs, have been met with skepticism from some quarters, with critics questioning the reliability and scientific validity of such experiences and the methodologies used to study them.

Beyond his work on consciousness and art, Nicholls has been actively involved in social causes. In 2004, he founded the Shahmai Network, an organization focused on poverty alleviation and human rights, participating in campaigns like Make Poverty History. His activism extends to social justice issues, including support for LGBT rights, polyamory, and feminism. He established the UK's first polyamory website, www.polyamory.org.uk, in 2009. Furthermore, Nicholls is a committed advocate for animal rights and veganism, having been vegetarian since 1992 and vegan since 2005, viewing veganism as a crucial step in ethical understanding that rejects exploitation.
