Mom had brain cancer, a mets from a previous beast cancer. Followed by WBR. She does get confused with poor memory but nothing significant. The last week she keeps saying someone is coming into her house at night. Stomps around. Turns on a light then leaves. Nothing is amiss or moved the next day. We live way out in the country. Our house is right in front of hers. No one has been here. Can WBR cause hallucinations? She is convinced of what she saw. Not sure what to do.
