Ejaculation, ghusl and namaz

i dont mean to sound rude bur this question is bothering me since sme1 mentioned it to me a few days back.
Is it true that if a man ejaculates during his sleep he doesnt need to do ghusl or chnge in ordr to read namaz?

if this is the case then isnt he in a state of januba?

personally i felt that this was wrong if he didnt need to do ghusl coz im sure hes in the same state as if he had slept with his wife n ejaculated therefore if he needs to do ghusl then y not if it happens in sleep?

once again dnt mean to offend just very confused
thnx
