Well, what this person is saying is, that if we do have a soul it must have weight, and it must occupy space, otherwise, we will have to change our basic thinking about time and space.
My mother and my sister both experienced out of body experiences connected with giving birth. My mother, on the table, hemmorhaged under the covers as the doctors were working on her, and "she" (her soul/spirit energy) floated up into a corner of the room, where it hovered (wringing its hands?) as she yelled, or tried to yell, "Look under the covers! Look under the covers!" Finally somebody reached under there for a diaper pin, and discovered her bleed-out. Her soul returned to her body when they stopped the bleeding. My mother was able to repeat what the doctors said and did while she was up in the air.
My sister, too, ended up in the corner of the ceiling. She was lying sleeping on the couch and began hemmorhaging. She heard a voice telling her to say goodbye to everyone she knew. So she started with her family. She had worked her way through her husband and half her children when someone came in and discovered her there, unconscious.
That has never happened to me, PTL, but my mother and sister were good Christians and did not lie. My mother would not even "swear" in a court of law, but she'd "affirm" - what the difference might be I have no idea.
