Experience While Meditating On A Mandala

I was laying down on my couch and watching a video of a mandala while meditating, all at once I was in a place where I was a torus field that was made of every color imaginable. I had no sense of my body or this reality. There was a vibration so intense that I had to pull away from it, I felt like I was being given all this knowledge, it's so hard to explain in words what I experienced. All at once I was back in my body. The base of my skull was vibrating so strong that I could not hear, I was totally freaked out, my heart was racing I thought I had been abducted or had died and came back to life. I immediately got up and went a got my mother and I told her what happened. I had this thought that there is no such thing as death and that time was a human ego structure and that we only live in the now. This experience changed my entire life and put me on a journey to find out what I went through. I started studying Enlightenment, and came to think I had a sudden enlightenment experience. I never have experienced anything like this in my life, I feel as though I was given a knowledge that I can't quite understand. Can anyone help me understand what I experienced. Thank you so much for your help. I am 43, this happened to me a year ago. I was going through a very rough time in my life, I felt suicidal, after this experience I had a calm come over me that made me realize that we are all one consciousness and that there is a reality that we can not see with our human eyes. That we are a higher consciousness and that our human body is but a parasite attached to our higher consciousness.
