that the same kind of thing that happened with my mom. she died and then back to life when everyone was sure she was gone... AND had normal brain function. she's perfectly fine now. she had an out of body experience (she could even tell me what clothes i was wearing whenever i went to see her at the hospital before she died) and said she saw an angel who told her it wasn't her time yet and God had more plans for her in life... she had to finish helping my dad raise my brother and me.
