Does it mean 'that the people in the hallucinations have the limited range of actions'?
Sometimes, she said, before the people come on, she may hallucinate
pink and blue squares on the floor, which seem to go up to the
ceiling. I said, "Is this like a dream?" And she said, "No, it's not
like a dream. It's like a movie." She said, "It's got color. It's got
motion. But it's completely silent, like a silent movie." And she said
that it's a rather boring movie. She said, "All these people with
Eastern dress, walking up and down, very repetitive, very limited."
"Limited" can mean "lacking something." I don't know the full context of this passage, but here's one possibility of what that could mean. The speaker might think that because the people in Eastern dress are walking up and down repetitively, they are "limited" because they lack more interesting, dynamic, and unique movements.
