He didn’t show up and apologised that he fell asleep?

So we were supposed to meet last night and he didn’t show up. Next early in the morning he send a message he was sorry that he fell asleep quite early around a certain time and that he woke up like 4 am.
Should I ignore? Just assume he is telling the truth or assume he is lying?
