Creativity of the Subconcious...

Its been a long time, haven't dreamt of anything lately, or rather should say nothing that I can distinictly remember after I wake up. Why? Has my subconcious exiled creativity? Does that reflect my own state? I am some what getting worried..
I think this is more to do with how much time I spend thinking to myself (talking would make me sound weird!). Thats the most probable premise that can have some effect on this change. Let me see how I can work on that...
