Hope so, otherwise it would be considered brain dead.
This is actually a rather deep concept. Do thoughts have meanings?? If it is just the thought and has not come to reality yet I would guess that it has meaning to the "thinker" and if that thought translates to the 'thinker's" behavior and others will have a reaction to this original behavior then yes.
Sometimes though the thought may just be fleeting..Like: *Walking though mall*...... I really wish they had those shoes in grey......OH!! ICE CREAM I will take that one and that one and do not be shorting me on those sprinkles...... Now I came to the mall for?? What??
In that instance no.
Yes , and so does your dreams , for all you fellow dreamers out there
Your thoughts can give something meaning.
they are to convoluted to tell most days.
