Your sentence is grammatical the way it is. However many would use "him". If you add "was" then "he" must be used.
Student or Learner
I am not sure if my sentence is correct. Would you please correct my mistakes?
Peter imagined millions of people lying in bed, awake, anxious for the future, just like he.
( I am wondering if I need to add "was" so that the sentence ends with "just like he was")
***** NOT A TEACHER *****
This is what I was taught.
1. "Peter imagined millions of people ..., just like him."
a. Many books tell us that "him" is necessary after "like," which is a preposition. (Some older books, in fact, say that "like" is actually an adjective: "just like unto him.")
2. "Peter imagined milliions of people ..., just as he was (lying in bed, awake, anxious about the future)."
a. Some books suggest that we avoid using "like" as a conjunction -- especially in formal writing.
