that wasnt a bad reaction, that was you getting high off the dxm and pseudoephederine. And how do i know this? Because i drink cough syrup occasionally recreationally for exactly that effect.
The having s**t tons of energy is the pseudoephederine, also you'll notice being happier, mood lift, being excited about things, also restlessness, and other related speed like qualities.
The feeling of your body drifting and not being where you think it is supposed to be is the dxm. DXM is a disassociative. Good pain killer. Will also make things look far away, or close up, make things look really big or tiny. Not really a hallucination, but it messes with perception. Things will feel the wrong thickness in your hand.
Also, important s**t here - If you have a small amount sex and masturbation is possible, however if you have too much, you will not be able to orgasm, and you may not be able to get an erection.
