Hello Joycelynn777: I'm certainly no expert with regard to autism. However, from what I know of it there would be no direct relationship. From what I understand seeing & hearing things in a person with autism is thought to be the result of stress related to social anxiety. I cannot speak to the question of your having had meningitis. The link below is to a discussion on The National Autistic Society website regarding the relationship between autism & seeing & hearing things:
