Creating and Visiting your own Archive while Lucid?

I was originally going to post the following in another thread but felt it would do better in its own thread.

Ive had numerous lucid dreams in the past, and only in the last 6 months or so have I looked up anything on them. And even after reading up on them I have been able to maintain some kind of control. But the last few nights have been random, I have been in my dream and realised and then felt myself falling back wards into my body.

In my dream a few nights ago I was in a shop, ordering a roll and bacon with egg, just as I'm about to tuck into it, I become all drowsy like I had been drugged, the people in the shop were asking me if I was allright, and I remember the sinking feeling like being pulled down by the weight of my body (much like I had been actually drugged) but couldnt control it, I then noticed this was a dream and slowly woke up being aware of the transition from Lucidity to being awake.

And my dreams this morning were very lucid too. I was talking with a news reporter slash guide type figure who was telling me to imagine a large building, to design it anyway I wished so I could remember it and come back to visit it. I imagined an archive type building, very grand, about 2 - 3 stories high but had many levels below ground, so it looked normal outside but stretched way beneath the surface. This was apparently an archive of my mind! I remember being inside it and it feeling very real,very grand in proportion, I got the impression of a vast amount of different coloured doors, and everything was marble, just like oneof those real posh banks in town that you get, but on a larger scale, lots of people around aswell, and as I walked downstairs I came to a sort of medieval play being performed on level between floors, lots of colours and spectators were taking pictures and walking in amongst the play aswell but no one seemed to mind all felt very normal and peaceful. I then remember falling backwards but being aware I was going back into my body as I observed where I was falling to.

I need to perform regualr RC's in order to ge the best out of my LD experiences as I always seem to just figure out I'm dreaming and shortly after (about 10mins at a guess) I would wake up and acknowledge I was lucid, then I would write it down if it felt significant enough.

Just felt I had to share this one. Anyone else visit an archive or been shown one in a LD? Ive heard of some kind of Archive you can visit through meditation or while being lucid that is like the one in Dream Catcher, but cant remember its name, I'm really interested in finding out more about it.

Peace
