advice?...you were just experiencing H.I. Hypno...something Imagery.

If it is HI, it means you are about to enter REM sleep...The sleep in which you have the most vivid dreams. If you get this at the start of the night...you are probably sleep deprived. Because usually REM would appear 5-6 hours into sleep.

Any specific help you want with this idea?

(maybe be less agressive next time you want help here too! Im not trying to be offensive...but having just looked up your first post...it can be quite tiresome answering common questions. Maybe it was just looked over.)
