Beta waves and REM (Rapid Eye Movement) brain waves can appear very similar on an EEG because both are associated with an awake, alert state of consciousness. Beta waves are present during wakefulness, where there is active, engaged mental activity. REM sleep, despite being a sleep phase, is characterized by brain activity similar to the waking state, including the presence of beta-like waves, which can make it difficult to distinguish between the two based solely on EEG patterns.
