A hallucination is a perception in the absence of an external stimulus that has the qualities of a real perception. Hallucinations are vivid, substantial, and are perceived to be located in external objective space.
A mild form of hallucination is known as a disturbance, and can occur in most of the senses above. These may be things like seeing movement in peripheral vision, or hearing faint noises or voices.
Hypnagogic hallucinations occur just before falling asleep The hallucinations can last from seconds to minutes; all the while, the subject usually remains aware of the true nature of the images.
This is a bitter hallucination. A group of love longers and constellations Something golden flashes through the air Synthetic stars changing the night sky Like each kiss he ever placed on your cheek I watch in silence as they falls to the ground They said I don’t belong here As I weave worlds unreal. A bitter-sweet Traumatizing Hallucination
