1.
the third of 4 possible plateaus when being high on DXM
Personally, the most enjoyable plateau; but not suitable to experience if you're trying to hide it from parents.

3rd Plateau: 7.5-15 mg/kg This level has strong intoxications and hallucinations. Things can become very confusing as your thinking processes are disturbed. You can sometimes daze-off into your own world, and get lost in your own mind. Trips in this plateau can sometimes be unpleasant.
