Links or advice to help me out with intro/cutscene?

So I have my main menu set up. And 2 Levels in the First Scene that my character can warp in and out of.

However, I don’t want the player to just be able to start walking around immediately. I want a little intro/cutscene/dialogue first. Where should I start?

Extra details of how I want this intro to start:

All player inputs should be disabled during cutscene, can’t move character…
Dialogue should be automatic without having to press ‘x’ to continue…
Character sprite transitions from sleeping to standing up before being able to move freely…
Memory sequence (this I can save for later the other’s are more important)

I made my level select and cut scenes into their own Unity scenes and swap to/from them as needed.
