hand gestures

[Naiad780]

If I remember right, spontaneous *physical* hand movements are called mudras.  Not sure about astral, though.

[Malevicta]

Last night as I drifted off to sleep, I noticed something strange. I was moving my hands rhythemically about, in an ongoing pattern. It vaguely reminded me of tai chi, as it was very smooth and fluid, almost dance-like in nature.

This isnt the first time this has happened to me, though this certainly was the longest it has gone on (and the first time it incorporated parts of my body other than my hands - halfway through I starting moving my legs as well). When I come to full consciousness, I always realize that it is not my physical body that was doing this, but my astral. Nor is it a conscious desicion on my part, it just kind of happens, always in a very detached, "hey-look-what-my-hands-are-doing-that's-kind-of-cool" sort of state. Like I am merely a conduit for what my hands are doing. If that makes any sense.

Has anybody else had similar experiances of hand gesturing, or have any idea what it could be? I would appreciate any ideas.
