What imaginary worlds did you create as a child?

I have found there is a fine line when we say "Those children live in a make believe world", or "Child, you have a wonderful imagination"! Does anyone truely know whats imagniation or whats "make believe"? How can we tell our young children that their invisible freinds are only "imagenarie" or "you're just making that up(and it scares people,so stop)"? Why should we say such things? Teaching young ones to hide their natural and instictive gifts leads to an unhealthy and dangerous lifestyle. They question everthing they do. They trust noone,including themselves. They feel everything they touch falls apart and noone truely gives a crap if they live or die. The simple act of actual  "Listening" has been lost over time. "To be seen and not heard", has held many,many gifted beings back from meeting their very own potential. So to the question "what imaginary worlds did I create as a child?", Who ever said I was a child? and just because your world was "imaginary", does that mean mine was?
If I was ever a child, My world is very real. It might happen that noone else can see the beings I see and more than likely, according to this world, my freinds are only in story books. Storybooks that I personally have not read and when those stories are read to me they are wrong in some of their details. Do I try and tell what wasn't quite right or do I say, "that was a pretty story but I don't want to hear it, again!"? Should we really care if anyone believes  in this lifecycle that our "make-believe" worlds could actully be that of  "other" lifecycles. How "imaginative" that would be?!
