Fall across and come across, drop across

Hi! Anyone, tell me please “fall across “and” come across” " drop across" is it the same?

Dear Terminator,

Let’s have a look at ‘come across’ and ‘drop across’ first as they are phrasal verbs.

If you come across something or someone you find or meet them by chance, this means you didn’t plan to find them. Here is an example:

Last night I was surfing the internet when I came across an interesting website.

If you drop across on someone, you visit someone informally without having arranged the visit. You can also say ‘drop by’. Here is an example:

If there is anything you want to see, just drop across.

Finally, fall across.

Here are some examples:

…shadows fall across (over) the land…
Hotel profitability levels fall across (throughout) Europe…[YSaerTTEW443543]
