Seeing a tunnel

[Gem]

[PLRGuide]

Once in the early morning after waking up with my eyes still closed, I noticed a spot in my inner vision. As I focused on this spot, eyes still closed, I realized it was a series of rings going down to a point and it seemed like they were moving towards me. The whole thing was only about the size of a USD golf ball held out at arms length when it started. As the rings seemed to move towards me I realized it was more like traveling in a tunnel. Within a few seconds I could see a pin point of white light at the end of the tunnel, and it too started to grow and move closer. At this point I am still very much awake with my eyes closed, and I kept squinting harder and harder because I kept getting the sensation that my eyes were actually open as the light moved close. As it grew larger the light looked like it was sort of dancing and swirling as it came closer and closer. The closer it came the harder I was squinting to hold my eyes shut because I really wanted to see where this was going, but in fact my eye were shut all along. I can only imagine what my early morning squinty face must have looked like as I tried harder and harder to close my already closed eyes. About 20 seconds into it, the dancing white light grew to about the size of a baseball held at arms length, and then started to fade, but the tunnel remained for a few seconds more. But as the seconds ticked by, and I kept trying to bring the light back I realized that the tunnel was less of a tunnel and more like the rings I saw at the beginning of this experience. Then it was over. I laid there and tried many times to bring back the light, but it was gone. Since then I have tried to bring back the light during meditation, and only sometimes can I sort of see the rings when I try. I have not been able to turn the rings back into the tunnel, and I have definitely not seen the dancing light again. This full experience only happen the one time, although I keep trying to bring it back. Anyone else experience anything like this?
