It honestly depends. If this is you, or a friend, I would suggest to see a doctor to be sure because they are the only ones that can make a professional diagnosis and provide the best advice. 
My input would be: either a coping mechanism or hallucinations.
Either way, it's nothing to be ashamed of and the sooner you seek medical advice, the sooner you can get a legitimate answer.
 
        
                    
             
        
        
        
Yes it is. Because it is always unsafe to use things like that, that are not secure.
        
                    
             
        
        
        
Hey There,
The best way to prevent heat exhaustion while exercising is 
D) Avoid exercise in extreme heat or humidity
While working out in the summer in a non-air conditioned place isn unhealthy and not safe. Doing this can lead to a stroke or heart attack. If it is already hot and you are adding on heat, that overwhelms the body. This action should not be done while exercising. Make sure you have a cool temperature building and are drinking lots of water.
Best Of Luck,
