'Slept' used in passive sentence.

No. Sleep is intransitive. Intransitive verbs cannot be used in the passive voice..

Thanks, how can I make it in correct form?

I was sleeping when you called.
I slept soundly last night.
I haven't slept in a week.

My main intention for the sentence was to express that some force made me sleep and because of that I couldn't attend the meeting. So can I write the sentence like: "I was made to sleep" ? or please give your suggestion.

MuhammedQasim,
That force that you referred to could be the exhibit of one of these mental- physical phenomenons: Anticipation, worry, obsession of something, or intense excitement, like getting on the plane for your first trip to Disney World. I couldn't sleep, just anticipating the first light.

MuhammedQasim"I was made to sleep"

In natural English, no nati
