Ego dissolution, or “ego death,” is the diminished sense of self experienced through psychedelics, meditation, or other spiritual or religious practices. In a state of ego dissolution, a person might feel that their identity or sense of being a separate individual has shifted. They may experience a sense of unity with the universe, a feeling of interconnectedness, and a profound understanding, all often tied to personal growth and self-discovery. After experiencing ego dissolution, people often report lasting changes in their perspective, attitudes, and behaviors, which could be attributed to neuroplasticity.
