I've been doing some reading about infrasound (see my earlier post). A good link is: http://www.answers.com/topic/infrasound
Of particular interest is the statement "Infrasound has been known to cause feelings of awe or fear in humans   since it is not consciously perceived, it can make people feel vaguely that supernatural events are taking place."
Reference 16 is John D Cody. Infrasound. Bordeland Science Research Foundation. See: http://www.borderlands.com/newstuuff/research/infra.htm
Reference 17 is V Tandy & T Lawrence 'The ghost in the machine.' Journal of the Society for Psychical research number 62, pp360-364. 1998. You can read the full text of this article by registering at the Library of Exploratory Science at: http://www.lexscien.org/lexscien/index.jsp
