Weird hallucination from vicodin!

[Mrhanky172]

One night swim was under the influence of about 25-30mg of vicodin. Usualy if swim tries to go to sleep while he is still high he gets bad insomnia. Well swim tried to go to sleep a little earlier than normal, and he was having lots of things running through his head. With his eyes closed all of a sudden an outline of a train came ROARING at him. It was like he could hear it also. This startled the living shit out of me. It wasnt really too scary, just very sudden and it made me jump what felt like 3 feet out of my bed! It was deffinently an experience to remember!

Has anyone had any experiances like this while on any opiate?
