The actress who voiced her in the original Japanese anime - Aya Hirano - only has to go to sleep.
Misa-Misa's foreknowledge was limited solely to the Fated death dates of all humans within her view. A fact that she was usually due to change anyway. Meanwhile the precognitive scope of Aya, who played her, knows no limits.
It would seem that the seiyū wins this round of preternatural skill acquisition and application.
With many a fan in conversation and the occasional interviewer too, Aya Hirano has told how she was born with her psychic gift. An hereditary clairvoyancy shared by her mother.
Precognition (or intuition - her rendering in Japanese as 特技 予知 could be read in English as either) was even listed in early profiles of the actress as one of her skills, alongside playing the piano and calligraphy.
Aya Hirano and her mother have predictive dreams, which later transpire to play out in reality.
Not quite the vision supplied by shinigami eyes, but I'm sure that both ladies are very grateful for that, preferring their version of The Sight over that suffered by poor Misa Amane!
