Many people feel they have had encounters with other dimensions and beings or presences that exist in those spaces. These dimensions have been reached through a variety of means, whether accidentally or externally initiated (such as through physical alien abductions, visitations from angles, or near-death experiences) or purposefully self-induced (such through trances, psychedelic drugs, or altered states of consciousness). These encounters can be described as blissful, neutral, or terrifying. There is a growing movement to promote scholarship and respected scientific inquiry in this area, while educating a broader community and integrating the information with knowledge from other disciplines.
