Tip toe through the Tulpas
Tulpa is a concept originally from Tibetan Buddhism and found in later traditions of mysticism and the paranormal of a materialized being or thought-form, typically in human form, that is created through spiritual practice and intense concentration. Modern practitioners, who call themselves "tulpamancers", use the term to refer to a type of willed imaginary friend which practitioners consider to be sentient and relatively independent. Modern practitioners predominantly consider tulpas to be a psychological rather than a paranormal concept
