Note 101 — Chapter IX

Hallucinations occurring in the ambiguous state between waking and sleeping are called by some writers hypnagogic. For the purposes of our investigation, coincident hallucinations occurring at times when it is doubtful whether the percipient is fully awake, e.g., when he is in bed, are termed "borderland." Their evidential value is, of course, somewhat less than that of hallucinations occurring when the percipient is unquestionably awake. (See cases 57, 59, 65, 66, etc.)
