Answer:
you cannot change this into passive voice.
Step-by-step explanation:
There is no way to make the sentence passive, at least not without doing violence to English syntax and sensibility and ending up with something that a native speaker would never utter.
Seriously: people say “I’m going to sleep.” We could say: “Sleep will come to me.” But we usually don’t.
People who are conversing spontaneously usually use the active voice. The passive voice is an option that can be used by us. But it is the exception, not the rule.
