Thread: How deep do you LD?

What kind of external signal inputs finally wake you up when you're LDing? I mean, many times I realized when I was LDing, it was easier that external signal inputs which don't represent any danger , such as people laughing or a car in the street, woke me up.
Is there any technique to get deeper LDs?

You sleep deeper when you are really tired so thats one way.

Make yourself tired.

I cant really tell what wakes me up sometimes...its like I know this is the end of the dream. And around that time my body wakes me up. Rarely wake up to people talking to me, and alarm or anything like that.
