There are many reasons why everyone should watch this movie:
1) this is illuminating on many scientific fronts, which is to say it will make you think about scary things
2) its inspiring without being inspiration porn because its made by the woman who experienced it. She was a videographer before the stroke and continues throughout – this is agency of the disabled
3) there are questions that are deep and uncomfortable
4) even when it seems to veer into the hokey, hippy-esque homilies, it arrives at a reality which is individual
4) David Lynch

…also, its subtly stylized. See if you can catch all the little touches that show you what she sees
