Yes, thats what the DILD technique is all about, realising your dreaming while still being asleep. And when you say "without havn to get up early in morn" do you mean getting out of bed or just waking up? You dont need to get out of bed and then go back to sleep (WBTB) to have a LD. And if you mean waking up, than like I said before you can have a DILD.
