Hi dreamers! New user here with some questions.

Hi everyone,

I was looking for some articles on internet about lucid dreaming and OBE and I am glad I've found this website. It looks it's a great source of information, help and inspiration for the book I would like to write for children about this topic– well I am still not sure if I can do that because English is not my first language but at least I am quite good at art and illustrations.
I have been experiencing lucid dreams and out of body trips for quite some time but I am still not very well trained. I would say that about twice a month I will have a LD without really trying hard. And I hope to have more that's why I will study the techniques people talk about here and share. Some of my dreams are fun, some are “steamy” (which is fun too) some very inspirational and some kind of scary.
I have a lot of questions but first I will have to search the forum because I would not want to repeat the thread.
There is one question however I have now. I did a quick search and could not find a thing but probably because I don't know the right term (my English).
Almost a year ago I had a weird kind of lucid dream. I woke up in a place full of light where something or someone presented how the universes are build. At first I thought “they” show me a bunch of transparent balloons but then quickly realized that was a model of the universes. I could look closer (without moving) and I noticed one much smaller bubble that was more in the back disappear (was sucked in) and another one show up in front. Those bubbles were in constant slow movement and they were connected and resembled something like fractals.
What is interesting is that was not the first time I was there because in a dream it felt the place was familiar. It was the first time I remembered it when I woke up. The whole experience was quick. I felt I have to focus what's in front of me and if I start looking around I would loose it. I sense the presence of some other people (or dreamers or consciousnesses- I don't know how to call it really). That's why I suspect there are people who saw the same thing.
When I woke up I told my husband about it and was so hyped up that I had “discovered” how the universe is build. Then I did the search on internet and it turned out there is a theory like that already. Bummer.

How do you call the experience like that and where can I find some more information about it? Was that a “cosmic server” or something or just a LD.
