There is no doubt in my mind that you've taken a tropane or mix of tropanes, the alkaloids present in mandrake and datura. Probably atropin.

You describe a state that is not a delirium (if that would be so, you would not be able to type this), but where the mental effects are clearly felt.

The effects can take a day at this dose, but they can also lat for two days.

tropanes are very dangerous and toxic substances. At this dose there might be no reason to panic or call an ambulance but DON'T TAKE MORE of them and at the moment your muscles start to feel to weak to even lift a drinking glass: immediately call for help.

Better to asl the nearest person (if nessecary your neighbours)to call the ambulance and watch over you before it arrives.

These are the symtoms of an overdose and a coming delirium.

But if it stays this way, don't panic.
