Sometimes when I’m asleep or I’m half asleep, I will utter slips of tounge that can be considered kufr but when I wake up I realize what I had said was wrong and I regret it. The wiswaas from the daytime affects me in my sleep, am I held for what I say in these states? Do I need to renew my Islam?

There is nothing on you. You just need to seek out medical help.
