just wondering if all dreams are tryign to tell you something or if maybe some are just there to keep you mind budy while you REM?

for example a dream i had
so it is in cartoon and Goofy (yes the Disney character) is in chains and shackles and is being escorted to a patty wagon by police. Rather then being is usual colour… he is black with a white belly… and covered in these disgusting white spots… and just before the police put him away he said “ don’t worry kids goofy will be back… when his leprosy is gone!” he said that between those weird goofy laughs.

the only reason i had that dream is because i was watching the simpson valentines enpisode eariler that day... goofy is in the dog pound in shakles and it thown in a gas chamber...
google watch simpsons online for free and watch epsoide 1912 if you wanna know what i mean... i think it's called spingfield love canal or something...

so do you think in a case like that a dream has meaning... or no
