[Footnote 47: To the same cause is probably due the use of four-poster beds in which the sleeper is completely enclosed by curtains and of those oldfashioned beds (still to be seen in some parts of the world) which could be entirely shut off from the rest of the room by a wooden partition or sliding door containing only one very small circular aperture for the admission of air.] [Footnote 48: Ferenczi, "Contributions to Psycho-Analysis," 189.

In Sir J. M. Barrie's remarkable play "Mary Rose" (which is full of interest in connection with our present subject) this piece of symbolism is duplicated--the "island that likes to be visited" being situated in a lake on a larger island.] [Footnote 51: Rank, "Die Lohengrinsage," 46 ff.] [Footnote 52: Freud, "Interpretations of Dreams," 243.

M. Barrie's "Mary Rose", in which a grown up son, on returning after many years to the home of his childhood, is earnestly warned and entreated by the housekeeper in charge of the (now empty) house not to enter his former nursery (womb symbol), a small room which is approached by a short passage (vagina symbol). He eventually overcomes his fears and boldly enters the forbidden apartment with a lighted candle (phallic symbol) in his hand. At that moment the ghost of his mother appears!
