When we search in the Wikipedia, dream is described as “the successions of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep. They can range from normal and ordinary to overly surreal and bizarre”.
In this edition, you will find part by part of that definition expressed by each individual. Dream in terms of vision when we are sleeping, dream in terms of vision you project about the future, dream in terms of its surreal sensation.
