theres been two different occasions where i have felt about 8 symmetrical pokes all at once, as if it were a machine of some kind within my body. 2 on the upper part up each leg, 2 on each side of my waist, 2 on each side of my lower abdomen, and 2 on each side of my middle abdomen. All of which went off at the same time. One night when i was taking a hot shower, i poured cold water on myself and i felt something within down both my arms and my torso. Its as if the unexpected change in temperature had disrupted something.
