When people claim to have experienced the presence of a dead loved one, a deity, or other spiritual entity, the way they knew the presence was there can vary widely, regardless of who they thought was present. Some say that they just knew the presence was there. Others say they saw, heard, or felt the touch of the presence. Others explain that the entity signaled its presence by arousing unusual feelings or by causing unusual things to happen. As part of a research team that attempted to understand such experiences scientifically, Ann Taves and a collaborator developed a typology of presence experiences designed to enable researchers to distinguish the different types of experiences that they wanted to explain. In this talk, Taves will explain the typology using experiences drawn from her research to illustrate and discuss how considering experiences as events can help us to understand the factors that interact to produce experiences of known presences.
