Stephen Fulder was the sample of one in the paper "How does it feel to lack a sense of boundaries? A case study of a long-term mindfulness meditator."

His descriptions of internal experience were characterized as a fading away or dissolving of the following senses:

• sense of internal vs. external
• sense of time
• sense of location
• sense of self
• sense of agency/control
• sense of ownership
• sense of touching/touched structure
• sense of bodily feelings
• sense of center/first person - egocentric - bodily perspective
