Link collections and show in forms

I have two collections. People (who they are, what they like, birthday, etc) and meetings (where, when, why, etc). I want to link them so that people can be assigned to meetings (and meetings can be assigned to people).

I’d like to create a form so that if you are creating a meeting, there’s a field that asks for a name, but that name is tied to a person in my people collection. I hope this makes sense.

Explaining a different way, just for clarity, if I’m creating a meeting event, there’s a form, one of the options in the form is “Name” for who I want to attend, and I can put in that box “Jessica,” but that field is actually a name of Jessica in a people collection.
