Greetings instructors,

Today I have a questions in regards to an experience that I had.
When I went to sleep, I woke up in the dream (A dream within a dream thing)
in a room basically identical to my room. I opened my eyes in that dream and
noticed in my peripheral vision, a dark shadow. Immediately I thought "Oh no,
not one of these possession/sleep paralysis things again!" I then closed my eyes
again to gather some willpower to face whatever it was. When I opened
my eyes again it was only a phantom of myself hovering over me, which was a black
and vaporous kind of phantom, with a grin hard to describe. It wasn't scary,
nor was it amusing. I've most definitely seen these before with different
characteristics. But this time I reached out my arm and noticed that my arm
went straight through, confirming it's an empty vessel of myself, an ego.
It wasn't very talkative and I returned to my body rather quickly after that.

I learned a lot from that experience, but some questions still remained.

Since these looks exactly like the description of a lunar body, is there a distinct difference
between an ego and the lunar astral body that we use to travel with? Or are we basically
shape-shifting between these different characteristics of ourselves? Because I have
basically hovered over people in the exact same way like this one in similar "dreams".

Best regards
Tristitia
