I don't have much faith in science, personally. I mean, I haven't got anything against science, but it's pretty limited. Science is only good for things in the material plane, and that's absolutely the limit. Anything spiritual is beyond the ability or scope of science to measure or validate.

That being said, there have been plenty of tests where brainwave patterns are studied in people while they do different things. Sleep, dream, lucid dream, meditate, etc. etc. There is a fairly distinctive brainwave pattern that people exhibit when they report having experienced an OBE. I'm not sure how it differs from a lucid dream, because I don't really care all that much what science has to say on the matter of spiritual experiences, but you could probably research it yourself, if you want.
