Train of thought

What is that thing called when they show you those little ink blots on a peice of paper and tell you to tell them what it looks like?  I can never find out whats thats called.  Whats that other test called were they say one word and then you say something back!!!  Still no clue, why do they have all these stupid tests but no names.  Well atleast I dont know the names.  I hate trying to remember names I cant ever do that, why cant every one be named steve!  Steve steve steve.  Like that monkey in that movie cloudy with a chance of meatballs.  That was a good monkey, that was a good movie!   I wonder if this is really what Nelson wants to see in a journal a bunch of random thoughts.  I gots lot of random thoughts I am not sure thats what he wants but then again this is my random page so I can write what ever random thing I want!  Is this random though if its suppose to be something we want to right about then is this really random if its what I want.  But if I am just writing down my thoughts as they come through me it must be random... or not random because I am thinking it.  Unless its completly random of me to write this just out of my head.  How does a train of thought lead you from one subject to something completly unrelated I mean not even close to the starting subject.  It also seems to happen alot when your talking with someone and both people just keep on talking until its at a completly random spot, most the time atleast its completly random.
