Hugh George Callaway (November 30, 1885 – April 28, 1949, pen name Oliver Fox) was an English writer, poet and occultist. Mainly remembered for Astral Projection: A Record of Research. .

Oliver Fox experienced his first astral exits in a dream at the age of sixteen. He discovered that even in a state of deep sleep he could control what was happening and influence the situation. He designated this phenomenon as a “cognitive dream,” since in a dream he received the knowledge that he dreamed about in reality. The secret was that while he slept, his mind retained the ability to think critically.
