Rapid eye movement sleep resemblance to waking life), and incorporation of instinctual themes. Sometimes they include elements of the dreamer's recent experience taken directly from episodic memory. By one estimate, 80% of dreams occur during REM. Hobson and McCarley proposed that the PGO waves characteristic of “phasic” REM might supply the visual cortex and forebrain with electrical excitement which amplifies the hallucinatory aspects of dreaming. However, people woken up during sleep do not report significantly more bizarre dreams during phasic REMS, compared to tonic REMS. Another possible relationship between the two phenomena could be that the higher threshold for sensory interruption during REM sleep
Eye movement in music reading unsurprising that the hypothesis was not confirmed. Four decades later, when evidence was being revealed of the bottom–up influence on eye movement in language reading, Sloboda (1985) was interested in the possibility that there might be an equivalent influence on eye movement in music reading, and appeared to assume that Weaver's hypothesis had been confirmed. "Weaver found that [the vertical] pattern was indeed used when the music was homophonic and chordal in nature. When the music was contrapuntal, however, he found fixation sequences which were grouped in horizontal sweeps along a single line, with a return to another line afterwards."
