Hallucinations on Cannabis and methylphenidate

[Milk man]

First I think you need to know a little bit about Swim's Dino's background. Swim thinks Dino had INTENSE paranoia(maybe a near psychosis break?)(http://www.drugs-forum.com/forum/showthread.php?t=59596).

Anyway, recently Dino's imagination has improved greatly, something he rather likes. It's sort of like reading a book, but he is able to imagine almost everything perfect(or as he thinks). For example, last night he saw an outside picture of his old house and then he tried to remember what it looks like on the inside(its been about ~6-7 years since hes been inside or seen a picture of it inside). He felt like he was able to reproduce it in his mind EXACTLY. When he thinks of an old memory, he can almost picture it(It feels as if he could focus a little harder, he could simple close his eyes and be reliving the memory).(all sober)

Is it normal to hallucinate on cannabis and methylphenidate. I read up a little more about methylphenidate and it's side effects include psychosis in some people. Would this be a tell-tale sign to stop drug use in dino?

Or is this simple because cannabis(schedualed as an Hallucinagion) compounds the effects of methylphenidate in Dino. If Dino is high on both, he can generally close his eyes and almost be like in a movie, running or playing a game or something. Its almost like he can do selective awake dreaming.

Dino tried this combination again, and was staring at his friends ceiling trying to go to sleep when he realised the ceiling seems to have the same pyramids shapes he saw when he was tripping at a friends house on XTC. He then thought he saw a shadow, went to investigate and summed it up as only his mind playing tricks. He then thought he should hide his car keys incase someone wants to take a joy ride in his car. He then calmed himself down, and was able to fall asleep.

Dino would also like to say that when he smokes just cannabis, he may get a slight auditory hallucination or swim's hearing improves. He generally can hear conversations of other peoples that are trying to keep their voices down and generally is right about most of what they talked about.
