When Laura speaks to the hospital doctors, there is a US flag on the desk between them. It seems to rotate through 90 degrees, depending whether it is seen from their perspective or hers.
Laura reports 'people' in David's bedroom, and later claims they poisoned him. There is no evidence of either, but a police officer takes her claims seriously. It seems inconceivable that Laura would not mention that she escaped from a cult while pregnant with David, or that police would spare a detective apparently to indulge her allegation of crimes with no evidence they even took place.
