Thank you very much for sharing this sounds like quite a wonderful experience.
I can not speak for everyone else, but I know I am usually quite scared or anxious before reaching hyperspace and I would assume most people are. When not in the proper mindset I have found myself shaking a little bit or being quite terrified with an increased heart rate. I consider small amounts of anxiety totally normal and, quite frankly, safe. If i get too scared however, I stop what I am doing and meditate.
I mostly wanted to touch on the subject of you feeling apprehensive in your experience and then "pushing forward". I think this is one of the biggest keys to having an enlightening or spiritual experience. It seems a lot of people who simply have intense visuals and no insight are quite frightened by what the see or feel and simply observe it. They do not delve into any emotions or feeling.
I think it is very important that you did this and I think in your future experiences, if you choose to have any, you will continue to get deeper and eventually learn more. Although you said you could not really comprehend the message I think it is telling that the experience ended on a high note with your radiating love and dissolving the negative feelings in your body.
Thanks again for sharing and of course these are just my opinions but I hope they were helpful!
