Kushal and Riya were watching a horror flick on tape-Riddle

Late one night Kushal and Riya were watching a horror flick on tape. Kushal fell asleep and dream that he was being pursued by the insane man from the movie who was attempting to murder him. He hide in a cabinet in his dream. He couldn't hear anything but his heart thumping, and he had no clue where his insane captor was. Kushal was terrified!
The video ended at that point, and Riya placed her hand on Kushal's shoulder to rouse him up. The shock of the situation was enough to cause Kushal to have a massive heart attack and die immediately. Is this true or false?
