Many investigators are convinced of the reality of astral projection.
Among the best known are Muldoon and Carrington, and Crookall. Together these two collected many cases of spontaneous OBEs which they amassed as support for the reality of astral projection. Many of the people who report OBEs have found the notion of astral projection helpful, and describe their experiences in these terms. The first is that many OBEs simply do not fit well into the astral projection framework. Also very few people actually report any cord, let alone the traditional silver cord.
