I was reading a English webpage ... and now I've come across a phrase:

Dream on

And from this, I remembered something of a piece of trivia about "ドラえもん":

It is known to fairly large population that the arrangement of letters "Doraemon" can be given as an anagram of the phrase "dream on" (with another o added). Search by "ドラえもん dream on" on Twitter, and you will find many tweets about that.

But what is the meaning of "dream on"? I looked it up with Wiktionary for this time ... and found that, as a verb, it means "to continue dreaming." Hmm ... okay, it's a neutral meaning ... there seems to be no bad connotation there at this very point.

But in the actual use of the phrase in the webpage, I smelled a somewhat provocative nuance... So the meaning of the phrase as a pure verb in the dictionary seems not to fit right with that usage.

Then I note another item below the verb ... it shows that, as a phrase, it is:

used to express skepticism or derision about the possibility of an interlocutor's statement

Ah, I see it. So it could be that if you suspect a hidden anagram in the title of the manga "ドラえもん," it is up to the one who interprets it whether it might have a nice (or neutral) or bad meaning.
