In April 1977, a patient from Harborview Medical Center, known as Maria, claimed to have had an out-of-body experience. During her OBE, she claimed to have floated outside her body and outside of the hospital. Maria would later tell her social worker that during the OBE she had observed a tennis shoe on the third floor window ledge to the north side of the building. Clark went there and looked out the window and could see a tennis shoe on one of the ledges. He published the account in 1985, and the story has been used in many paranormal books as evidence a spirit can leave the body.
Hope this raises your spirits!
