Oh yeah, I used to 'fight' with sticks a lot. Always when in a forest I had to search the perfect "sword", lol. I was never good at it though, but I liked to dream I was.
I also loved climbing onto things. Trees, roofs (yes, roofs), small walls, everything, lol. I aspired to be the next Ezio! XD
Also fantasy-based roleplays and such, like "a hero's journey" kind 'o thing. And now I'm here LARP-ing... not much has changed, lol!

And yeah, dino's are awesome! Now I shifted to dragons, which are basically dino's, but with more fantasy and creativity!
I dreamed of having a treehouse too! Me, my dad and a friend worked on making one for hours, but then the next day the bullies destroyed it. (we didn't have a tree in our garden, so had to use a tree in a nearby patch of greenery) I and a friend from the neighbourhood dreamed of making our own 'fort' and then totally own the bullies from over there, lol. We even made plans -like little kids do- but obviously never got through with it.
