Whatever fix we get out of the unknown through imaginings should be based on the known facts based in reality. Do we really see our future accorded with our attributes, our abilities, our talents?
If you feel you are able to function and behave in a way conducive to your fantasy, does it mean you should carry it out? Do you know the difference, not only between right and wrong but the element of what makes a decision be accurately 'yours for the taking'?
Now there is that factor to decide whether its okay to hold inside your imaginings. By this meaning, letting out or utilizing the act of purging. Purging out from your mind what is so wild and so profound. Do you really want to carry it out?
It's basically your instinct to tell you whether your actions have meaning. Your instinct can't help but probably make you "go for it" unless you use self-control. Your instinct can most likely tell you it doesn't have to be. But will you listen to it? How would it be to think carefully your ways, though it can seem to be non-existen for some people.
The manifestation of this desire is actually an example of a fulfillment of 'circumstances played in the mind' (which are not necessarily true). It is called delusions. A delusion can be cathartic by relieving the emotional tensions. This term cathartis best used to explain how it causes someone to reevaluate and receive insight. Yet if only they could learn the truth. The truth is, it could be a bad fantasy or just not even factual yet it pervades the mind, not in quantity or quality but in in filling out the activity felt through helplessness.
A dream differing from a fantasy could mean a calling or goal to pursue with recognition in regards to seeking counsel or advice from others. If he or she is satisfied by his or her individual decision about the dream, then so, the better only if the result of these dreams or goals are morally sound.
