This same experience just happened again in a different form; it’s interesting its the same moon phase (one lunar cycle difference). I cannot see any connection to my astrological chart with the transiting moon, in fact there are no planets in that section of my chart, moon as I woke up this time is in the first degree of Capricorn in my presumed seventh house moving towards the eighth (last decan). It may have a connection to my guru, as I was listening to several old satsangs on Patanjali’s sutras and the siddhis; the last one before sleep was on awakening the biomemory.
This time rather than my arm, it was intense curiosity or trying to rationally solve a problem. In the dream plane I was cleaning up my room in a house that looked newly moved into, getting rid of garbage. I saw a bookcase containing a lot of books with hoary knowledge in it, but to access the bookshelf I had to bend down. I realized the bookshelf had to be at least one shelf higher in order to be optimum for me to use it.
As I start looking around and trying to solve the problem myself, I relate the problem to a parent figure (my mother, who is a retired teacher, hence quite possibly my guru in disguise). My parent answers me that they may be able to buy a completely new bookshelf for me soon, but I explain to them I’m sure I must be able to find items from around the room to put together the new shelf that have the right amount of tensile strength and size etc. I keep looking around the room for objects that can work.
When I can’t find any, my rational mind now fully awake in the dream decides to go look in another room for what I need to solve the problem, and I promptly wake up from the dream, immediately fully awake in my body.
So, first experience used physical sensations and trying to move a body part to go lucid, while this one used applying the rational mind to a problem in the dream. I have had RoD in my stack but again, several weeks ago.
Its possible there may be my gurus involvement here or meditation/awareness techniques prior to falling asleep aiding the level of lucidity, but all I can do for now is report a repeat experience of almost achieving lucidity with a RoD earlier in the month.
