my father did one a few years ago
in the test he actually went 4 3/4 min without breathing then a huge gasp of air fine for a few breaths then again 3 1/2 no breathing
he a machine that esentualy blows air into his nose to keep his soft palete from relaxing and causing him to stop breathing.
after the first night he called a "family meeting" :smart: and told us about his dream he had :doh: :nuts: :???: :shake:
we all called him snuffy for a few weeks :clapping: :rotfl2:
apairently he had not had a dream about any thing for 20 years or more :(
