Why Are Near Death Experiences So Similar?

In 1977 a migrant worker known as Maria went into a cardiac arrest in a Seattle hospital. While the doctors were resuscitating her, Maria found herself floating outside the hospital where she saw tennis shoes on a third-floor window ledge. Once recovered, Maria spoke about her experience with a social worker and went into detail about the shoes. The social worker then went to the window that Maria indicated and not only found the shoes but claimed that from where they were placed there was no way Maria would have been able to know that they were there and describe how they looked from her room.
