I usually have to take corticosteroids every year after i get a chest infection due to athsma. I find that if I stay on them too long I start to get the crazies and quiet murmurings like voices in my head :)
I tend to take high doses and then cut it out after 3 days instead of tapering it out as that stops the side effects. Occasionally that method of taking it doesn't fix the infections but it is a hell of a lot better than talking to yourself

The acid flashback dreams are cool though

I am sure that wont happen to you though *grins*
