Science and scientific evidence is completely valid
for the physical world and its inhabitants

lucid dreams, consiousness, OBE and metapysical things like that most scientist laugh at because there is no scientific proof therefor it doesnt exist in their minds

in a way they are right, in the physical universe these things do not exist and cant be proven by scientific technology because they are nonphysical concepts....they dont exist in our realm, these things cannot be measured.
