Tunnel or hallucination?

I’m not sure if this is the correct forum to post this. I’m still not sure what it was…

When I was 17 I had tonsillitis, strep throat and the flu all at the same time. I remember getting up from the couch about 2 or 3 in the morning. Went to the restroom and after I was finished I turned to look in the mirror to see how bad I looked; but the mirror wasn’t there. A tunnel opened up directly in front of me; pulsating, alive. It looked like lightning or a kind of white energy interwoven around the outer edges of a black tunnel. In the center of this thing was a pinpoint of white light; which became extremely dominate within a fraction of a second. Then I felt a rushing sensation as if I was being forced through the tunnel at a great speed. I was scared out of my mind and all I could do was close my eyes and shake my head to try and get rid of it. But when I close my eyes it was still there. I fell up against the china cabinet we kept our towels in; still shaking my head. Finally the image faded and I made my way back to the couch not able to see a thing. I sat there for I know a good 20 minutes until my eyesight returned.

You know, I never really thought about it for many years, I just blew it off as a hallucination. But now I’m not so sure. I can still see the image as if it just happened.

Any input would be appreciated.
