Yes there is a spiritual dimension and there is a physical (matter) dimension. There is reality and there is appearance. Truth cannot be found in matter dimension. Only apparent conditions. Bible says things seen are temporal but the things unseen are eternal. All our understanding of life is geared to the visible.
We are occupied by the ‘sweat of our brow” and the application of our minds in expanding and using the visible. Anything not within the compass of our reason we consider crazy. We find in the Bible recordings which are supernatural which cannot fit into our interpretation of normal cause and effect. These happenings are products of another dimension, the spiritual dimension. This is beyond the scope of human thinking. Either they belong to the absurd or they belong to the real and we are in the absurd, who discount them and claim the only real to be our labored efforts. Yes there is a spiritual dimension and life.
