Initially, it spread to about that extent, and eventually to about three-quarters of the entire area. It felt like electricity, although it might also be described as light. It's closer to the sensation of electricity.

Initially, the following areas were covered:
- The back of the head
- The right side
- The lower half of the head, slightly towards the back

The sensation was like a net, although the mesh was quite large, like the seams of a soccer ball. Initially, it appeared as a net-like pattern, and then as it permeated, the mesh became less noticeable.

Initially, the following areas were not covered:
- The upper left side
- The top of the head

However, gradually, the electricity permeated the entire head, although not completely.

I think this has further promoted the activation of my brain.
