AstroBoy, welcome to the Nexus.
spice can give quite a strong experience and leave quite the impression as you seem to know by now. I would suggest trying lighter doses a few times before going off the deep end again. I've never had to vomit during spice (thank god). Also if you don't have a source you trust you really don't know what kind of impurities are in whatever you have there, so I highly recommend extracting it yourself. It's very much worth the effort and a very nice experience IMO.
As to your questions: They cannot be answered generally. There are many levels you can try to find personal answers for these questions - the psychological interpretation (like with dreams); the *real* interpretation, considering that what you saw was really there and taken at face value; mythical interpretations, tying it into some kind of larger context spanning from ancient times into the future; the magical/shamanic interpretations; ... whatever else comes to mind.
Important IMO is that you make something of it. If you don't it's just an experience, no matter what the significance. If you can gain something for your life from it, whether it is just a level of awareness you feel is added to your every day experience, or some kind of change in your every day behaviour, your diet, your way of dealing or thinking about people etc... then you've made something of the experience. If it served to make you understand yourself, or the cosmos, or revealed to you that you don't understand yourself or the cosmos, and this makes you ponder, then you have begun working with the spice

There are many ways that these experiences can affect us; it's not always about a take home message or a moral-of-the-story kind of thing. Sometimes they just help us become more open in our ways of thinking, change our perspective, our reality tunnels etc. Sometimes they can clean out some bad patterns.
That is not to say that they can't also cause some negative effects, physical, mentally or spiritual, and one should always pay close attention to these things in order to know if one should proceed on the path one is on.
Concerning your membership, be patient, it will happen soon enough. Your questions and reports can be posted here in the Nursery and will certainly be answered to our best knowledge and abilities. Just ask away.
Once again, a warm welcome to you.
Enoon
Buon viso a cattivo gioco!
