Alucinar
To be blown away, shocked, or to flip out. It also means to be tripping or deluded, imagining things that are not real (the expression alucinar en colores is a common way in Spain to describe being completely out of touch with reality or being totally stunned).
When he told me he had won the lottery I was left alucinado. That guy alucina en colores if he thinks I am going to do his work.
