How do altered states differ from everyday awareness?
Short Answer
Altered states involve significant changes in perception, cognition, emotion, or self-awareness that deviate from ordinary waking consciousness through neurochemical or neurophysiological modifications.
Why This Matters
These states occur because various factors—including substances, meditation, sleep deprivation, or sensory isolation—disrupt normal brain network connectivity and neurotransmitter balance. This disruption results in altered temporal perception, modified sensory processing, and changes in the default mode network that typically maintains our sense of self. Understanding these mechanisms demonstrates how flexible and context-dependent human consciousness actually is, revealing that our everyday awareness represents just one possible configuration of brain activity.
Where This Changes
The boundary between ordinary and altered consciousness exists on a spectrum, with subtle shifts occurring during daydreaming or mild fatigue. Some individuals experience naturally occurring altered states more frequently due to neurological differences or heightened sensitivity to environmental triggers.
