A general writing or a novel demands some kind of extra effort from the audience as they require some form of adjustment in getting synchronized to the reader’s thought process whereas fantasy novels convince the readers and carry them away to the authors’ imaginative world which requires less or no logic, which is very essential while dwelling inside a recital/storytelling.
A reader is just involved in the creative circle that the novelist has created because it’s a new world where the readers don’t belong and hence have no apprehension to process out in the back of their minds about the sequences happening. This is a big relief to any reader as their only job is to dive out into an innovative zone and experience a true spirit of ingenuity.
Kids and Young Adults:

“Fantasy books are very important to kids’ brain development and dreaming is another human
survival mechanism”, says research. Entering a dream state regularly refreshes the mind to cope with the demands of a new day. In dream deprivation experiments, where subjects are deprived of dream-state sleep, mental deterioration occurs rapidly. Without dreams, without fantasy, we become shells of our potential selves.
Fantasy is therefore important to mental well-being, particularly for the small children/ young adult reader. It provides a momentary escape, a release. It helps increase the potential of one’s imagination to solve life’s problems. It can help resolve emotional conflicts and alleviate anxieties.
The key element of the fantasy fiction genre is magic. Fantasy novels may be romantic, historical, action-packed, or all three, but the element of magic is what sets this genre apart from all the others. Fairy tales, myths, and legends are part of the fantasy genre. Stories featuring wizards and sorcery, unicorns, and dragons, are fantasy. Through fantasy fiction, readers are allowed to visit a world they never would have been able to otherwise.
Although all fantasy stories are unique, some characteristics are common in the genre. In general, the conflict in fantasy novels is of good versus evil. Most fantasy fiction also features great details, with settings, creatures, words, and names that are often created by the author. Fantasy novels must be read carefully, for their settings and characters are not familiar in everyday life.
The Powerful Elements of Fantasy :

Language: Whether it’s a fabricated language, or it’s the manipulation of how an existing
language is spoken, new languages teach us the importance of language abilities and their
skillset. The inclusion of fantasy language heightens the reader’s ability to transport themselves into a different world.
Supernatural Creatures: Elves, dragons, dwarves, enchanted plants, vampires, werewolves and talking animals. The right combination of these, with a few humans, creates an essential dynamic between the real and the surreal. These kinds of character introductions help us identify ourselves either being one with them or consider that we are humans, which establishes a strong mind-level analysis in understanding the practical life that individuals are associated with.
Magic: Characters perform some form of magic in most of the fantasy tales. Most often the characters possess a very strong magical ability that they don’t initially have, or don’t know they have, and learn to develop. This magic inside a fantasy is important for us to understand that in real life, hard work is the solution to many potential abilities which is true magic for a cherishing life. It also teaches us that magic comes with a price hence lets us analyze the flow of a practical realm and its abilities.
Love: A love interest exists to pull at the heartstrings of readers. Usually, the love interest of the main character is unattainable. It helps if they are not of the same genetic make-up (i.e., Human and Vampire, Human and Elf, Werewolf and Vampire.) This makes a point to a world that love is imperishable and is a must in any life, that exists parallel to us.
The Villain: The Villain must be extraordinary and not easily defeated. The villain is often not revealed in person until the end of the story, to create the most impact. This gives the most important factor for life that without an antagonist in life, a protagonist has no aim to survive.
Battle: Without an epic battle in which the hero is nearly defeated, ultimate victory would not be so sweet. This teaches the importance of life struggles that we need to realize and work upon to sustain being effective and imperative.
The Weapon: A wand, a sword, and the mind abilities such as magic, are the special tools that have to be special in not only their capabilities but also in the reason behind their existence. These show the importance of our qualities /abilities to be utilized as tools for a successful living.
Conclusion
When life is hard, there has always been a remedy existing, ever since humans were introduced to verbal and non-verbal engagements. These originated as Fables since then and slowly evolved into storytelling and from thereon many forms of it with a fantasy world setting and a problem- solving background that gives a solution to any/all kind of glitches that induce the human brain to think and react to situations and create a new scope around them. For a potential reconnaissance, fantasies set an important consonance.
