The presence of theta waves and sleep spindles indicate that Natasha is in stage N2 of the sleep cycle, which is a relatively light stage of non-REM sleep. This stage often makes up the majority of sleep time and is characterized by a decrease in muscle tone, slower breathing, and a decrease in heart rate. It is not likely that Natasha is dreaming or in REM sleep, as the EEG does not display the typical patterns associated with those stages. Since the noise from the can of soda did not wake her up, it is also unlikely that she is about to wake up.
