The Limits

Besides each entry within an array occupying one of the 500 available string or variable slots available for your Dream, entries also share the same limitations of strings and variables.

Variable entries can handle numbers ranging from -32768 to +32767. They also can store a max of 1000 numbers if they're all used, because they have the .x and .y coordinates (while arrays that use strings can't, due to not having .x and .y available).

Meanwhile, though entries within string arrays can be 4096 characters long, they also contribute to the total of 32,000 characters limit across all strings in your Dream (this includes spaces).
