The most common type of hallucination is visual. In this hallucination the victim actually sees things such as horses, elephants, unicorns or anything which are not there in reality.
Hallucination can be caused, not always but sometimes by neurological diseases like Alzheimer’s disease, dementia, migraine etc. Experiencing hallucination doesn’t always mean that the victim is suffering from a disorder. Hallucination may also be caused due to drug or excessive alcohol uses. Sometimes, a belief is so much strong that it overcomes the external stimuli and hence the victim observes and experiences something which is little or total fiction.
Sometimes it is modified form of reality, such as a very thin fashion conscious girl may percept her image in mirror as very fat. Sometimes it can be completely imaginary, such as meeting to angels or Jesus Christ.
The perception in hallucination is so strong that it is hard to deny it. Note that there is a solid difference between hallucination and dreaming. Dreaming happens while you are asleep and unconscious but hallucination happens while fully awake and in full consciousness and awareness. Here explores for you the different aspects of hallucination and the methods to trigger it.
