Vladimir, who had been asleep, could be seen having subtle eye movements despite having his eyelids closed, hinting that something was messing with him while he was in his slumber.
However, at the moment, he was unsure of the cause. Nonetheless, something seemed to be trying to interrupt his good sleep, something that he hadn't experienced much since he joined the government, and due to his history as a former KGB agent, he was conditioned to always live with a perpetual sense of paranoia about someone or the other planning to attack him, since there was a possibility of retaliation from the people whom he might have crossed with during his espionage days as it was likely that would target him and try to seek revenge from him.
With a history of sleep deprivation due to constant vigilance, he would always be wary of any disruptions during his much-needed rest.
