Lucid dreaming—becoming aware that one is dreaming while still asleep—has long attracted interest across neuroscience and consciousness studies, particularly as researchers explore how waking cognition and dreaming cognition may overlap. According to Berry, both headband-style systems are being developed to test whether low-intensity focused ultrasound could influence brain activity in ways relevant to lucid dreaming research. He emphasizes that the work remains exploratory, aimed at investigating whether targeted stimulation might interact with neural processes linked to lucid dreaming rather than demonstrating any specific outcome. Lucid dreaming research has similarly expanded, increasingly focusing on real-time interaction with dreaming and treating lucidity as a multidimensional experience involving awareness, memory, perspective and varying degrees of influence. Similar research published in the journal Consciousness and Cognition has explored methods intended to encourage lucid dreaming outside laboratory settings, including cue-based techniques adapted for home use.
