Welcome to our hallucination

• Visual hallucinations. ... 
• Auditory hallucinations. ... 
• Olfactory hallucination. ... 
• Tactile hallucination. ... 
• Gustatory hallucination. ... 
• General somatic hallucination. ...

And the list goes on. 

I have encountered the first three but no doubt, I will be set upon by the others before I die.  

I have just concluded that life is a consensual hallucination;  we don't really exist, we are just figments of each other's hallucinations. Somehow we have found a way to hallucinate a common hallucination.

For some reason, we attempt to discover what mechanisms control our existence, to explain the unexplainable, to find order in our mutual chaos.  Why bother? You will just develop theories, ideas that can never be proven (or is that "proved"?).  For example, the big bang theory.  What a load of dung!  How are you going to explain the existence of the singularity that you vaunt started the mythical explosion? Why can't you accept that not everything has a beginning and an end? The only certainty in our mutual delusion is "change" which is inevitable in a chaotic system.  Your theories will remain theories. 

But. for that matter who cares?   

  Thus endeth today's rant.

BTW, hallucinations are not uncommon in PD
