Of course, it was already apart of the information on the description and condition part.
But doing that wouldn't help protect the user at all since Enter Sandman's physical form only exist in the target's dream, and the user already has a buff of enhanced endurance and stamina that was given by the stand, with the exchange of a permanent insomnia and nullified development potential.
