i know exactly what ur talking about... ive had it too, but not only just my name being called, more like door slamming or whatever....

if i can remmber correctly, this is an auditory hallucination from being half-awake/half-asleep.... just like when ur falling asleep, those first few minutes when ur falling asleep are full of mental hallucinations, and then ur knocked out....

but i dont remember what it was called... im not sure if its hypnogogic something... i dont know, but it is something ive had happen to mee too...
