““Worse and somehow embarrassing affair are "ghost" dreams, from which the dreamer only remembers fragments, and very short snippets of events, after which the next morning is left only a vague feeling of a messaged received. If the "ghost" is repeated several times, it is certain that it is a dream which is important for some reason. Then the dreamer, through concentration and auto-suggestion tries to force the dream again, this time a more specific "ghost". The best result are to force oneself to dream again immediately after waking up - called "hooking". If the dream does not produce a "hook" they try and produce a vision during one of the following session by concentration and meditation prior to going to sleep. Such pressure programming is called "anchoring".””
