When wanting to connect to signals you need to have a reference to the script that emits that signal. So I want to know, is there a way to connect to a signal without the reference so that you'd just have to type the name of the signal in the connect() function?

It's pretty common to do this with an event bus autoload. The idea is that you define the signal in an autoload, and then connect and emit form there:

event_bus.gd (added as an autoload named EventBus)

signal my_signal()

player.gd

func _ready() -> void:
    EventBus.connect("my_signal", self, "on_my_signal")

func on_my_signal() -> void:
    print("my signal was called")

some_other_file.gd

func emit_signal() -> void:
    EventBus.emit("my_signal")

This way player.gd and some_other_file.gd don't have to know anything about eachother... they only have to know about the event_bus.gd.
