Ok, from what Ive read HH occurr within 30 minutes of falling asleep. I am pretty sure that I have experienced these alot. The jerking sensation of falling,etc. However I have a lucid dream in which I know I am dreaming. For instance.....I dreamt that I was having a conversation with my husband, I saw a woman in a long flowing floral dress walk thru the house...at that point it struck me odd and I knew that this woman should not be in our house and I knew I was dreaming. I woke up on the couch next to my husband, we had fell asleep watching tv. I tried waking him up to get him to go to bed and when I looked up....I saw the woman again and then realized again that I was dreaming. At that point I was frightened. I ask my husband if we were awake he assured me we were. He was sleepy, but said of course your awake. I told him that he needed to wake me up, that I was dreaming. I kept telling him to wake me up...and that is when I really woke him and he woke me up. This happened several hours after going to sleep, so I dont think that this was a HH. Have you ever had this type of over-lapping lucid dream? Is it common? Maybe I just dont know what to do with it and I just get scared because it is a new experience. This is about the 3rd time in the past couple of weeks that I have had this type of over-lapping dream.
