“I keep hearing voices and I am convinced that there are aliens. My friends laugh at me and say there is no such thing but I know that I hear them and so I know they are there. How can I prove them to my friends?”
I am not going into whether or not there are aliens as honestly I do not know the answer. But if you are hearing voices, you might need to get checked out with your Doctor. Hearing voices may be a symptom of schizophrenia. I am not saying that you are schizophrenic, but you might want to rule it out with your GP. If you are suffering from schizophrenia, your doctor may be able to prescribe some tablets to deal with your illness.
