I knew about mag pillows, then heard a web radio person say he used one and it improved his meditation and reduced his ego...so I looked at buying a manufactured one, then decided I would make one for 20 bucks.

The pillow may be a temporary catalyst, but unless we live a life practice conducive to dreaming, I imagine the extra stimulus it provides will garner less effects over time. Can't fool nature with cheap tricks so to speak.
Towards this end I will mention a few other things that we can add to our dream friendly lifestyle.

Increasing Dream Life:
• Raw Diet—Conductivity and energy (enzymes-sprouts), increase %
• Green—Regeneration with raw chlorophyll with plants grown on remineralized soil
• Sungazing—Dawn and Dusk, brain charging with photons
• Nature—Soul recharging, negative ions
• Novelty—New experience, neurogenesis
• Visual Stimulation—Art, movies, Mind'sEye Videos, sacred geometry
• Vision Quest—Questioning, surrender, exposure to the elements
• Relationships—Stimulating, meaningful, purposeful, creative
• Herbs—Valerian, Chamomile, Calea sacatechichi, Mugwort, Syrian rue, African dream herb, Blue vervain
• Melatonin
• 10-20 minute stretching/rolling on the floor, spinal rolling
• Hanging from the hips over a bar for 5 minutes in passive stretch
• Deep breathing prior to sleep
• Toning—huuu, hmmm, Ommm etc...cleans brain
• Theta wave CD by Jeffery Thompson
• Drumming, dancing, gardening, mud/clay baths, mineral pools
• Living a virtuous, abundant and giving life, regenerating the earth
