Same. I don't think scientists have discovered everything "out there", I'm sure there are other things that have yet to be explained, but until then I'm just uncertain...
As an undergraduate scientist, I can reinforce your idea that we have yet to develop a grand unified theory involving the whole cosmos. Hell, we don't even have a tried and tested form of quantum gravity yet (with the exception of Dr. Carlo Rovelli and Loop Quantum Gravity, but we'll see how that plays out).
Objectively speaking, paranormal claims have been tried and tested for thousands of years. The belief and faith in such claims dropped dramatically since the inception of the camera and probably quite as easily jumped back up as high after Photoshop was created. In modern days, the best evidence we get for claims such as 'spirits' and 'ghosts' usually lies in the deceptive words of mediums, psychics, and other kinds of snake-oil salesmen trying to separate people from their hard-earned money.
Regardless of what scientists "know", the academic realm still keeps an open (albeit, very skeptical) mind. Anecdotal descriptions and personal experiences, however, don't lend any credibility to those claims.
