hi katrien
there is for me a sense of the liminal, for lack of a better word, in your description of "hanging between states". when bringing up the  sensory or perceptual realm, i wonder about experiencing this kind of subjectivity not through one of the senses (watching or touching, etc), but via the conflict between senses -- conflict between eyes and ear, for instance, as in feeling like one is walking upside-down, or falling and sitting at the same time.
squizy is a great word.
