Characteristics of this condition include abnormal behavior during REM sleep, REM sleep without atonia, and the enactment of altered, unpleasant, or violent dreams.
Sleep paralysis is the temporary inability to move in the transition into or from sleep; it is thought to result from REM sleep atonia manifesting in the transition between sleep and wake.

Parkinson's disease (PD) and PD-like conditions (synucleinopathies) are often characterized by the suspension of normal REM atonia.
22] REM sleep correlates highly with dreaming and is characterized by bursts of rapid eye movements, an increase in both respiration and heart rates along with atonia of many limb, trunk and neck muscles.
