To dream a teacup:
there'll be a storming moral dilemma that doesn't merit the anxiety it causes.
(Or it could just mean you will wake for breakfast with an epic thirst)
To dream a seagull:
someone will intimidate you in your solitude and demand your payoff with menaces.
(Or it could just mean you are going on a coastal holiday)
To dream a dentist:
someone will cure you of an irritation as a consequence of extracting something, which though mundane, you have cherished for your entire life.
(Or it could mean that you have an appointment tomorrow)
