A noetic quality is a term used to describe a wide variety of mystical, spiritual, and religious experiences. These are often described as noetic qualities because they can feel real to the person who is experiencing them. People have described religious, spiritual, and mystical experiences in a variety of ways over the years, leading to the abbreviation RSMEs. For example, someone who participates in a religious ceremony involving a shaman might take a psychedelic substance as a way to trigger a certain experience. This could be considered a noetic quality.
