hey, I have a friend that traveled for 5 days and he tried cocaine, marijuana, crystal meth and drink alcohol and he kept hallucinating that 10 police members entered the hotel and crashed everything and attacked 2 of his friend , he stayed awake for 4 days only had about 1 hour of sleep daily , and now since they came back to his country, he kept telling us what happened there including his hallucination , and the way he was talking was very serious and he looked terrified and nervous , he was itching his upper-body and face , His face was pale and bruised on his cheeks.
