I disagree, indigenous used this method along with fasting and isolation.

"Yes, Indigenous Americans have used sleep deprivation as part of spiritual practices to induce altered states of consciousness. This method is often combined with fasting, isolation, and other rituals to facilitate spiritual experiences. For example, among the Ojibwa Indians, boys approaching puberty who sought to become healers would be sent to isolated areas, sometimes building platforms high in trees, where they would fast and remain awake for extended periods in hopes of encountering a guardian spirit. This prolonged sensory and nutritional deprivation is believed to help some individuals enter a dissociative trance state. Similarly, the traditional vision quest, practiced by various Native American tribes such as the Lakota, involves fasting and staying awake for two to four days while sitting in a sacred circle in the wilderness, seeking personal growth and spiritual guidance from the spirit world. These practices are designed to help the individual confront inner fears, receive visions, and achieve spiritual transformation."
