I won't call it laziness or being unmotivated. I'd call it a deficiency in niacin to be rectified by eating foods high in tryptophan and exercising more often so that your brain can uptake tryptophan without fasting. Will help your brain make melatonin and dmt and enhance your quest for lucid dreaming as well :). I recommended your brother try welches grape juice concentrate. Like an hour before bed. Mineral in grape juice is said to accumulate in pineal gland and help maintain increased dmt levels. (them hops and grapes man)
