Vanishing Waves (2012) on Netflix

Plot summary

After a long preparation, a team of neuroscientists begins a research project. Lukas, a matter-of-fact member of the group, is to be linked to the brain of an anonymous comatose patient, entering her mind to observe only. On his second attempt he finds himself in the vivid imagination of a young woman lying unconscious on a beach; she wakes and kisses him, and passionate encounters follow. Surprised and irritated, Lukas tells his colleagues he saw only shadowy impressions and says nothing of the woman, then pushes for more sessions. The bond between them grows while he withdraws from his colleagues, his worried friends and his long-time partner Lina.
