Yes, but it went another dream level deeper. I woke up from a dream (level 3 --> 2) and was telling my family about it. Then I woke up again (level 2 --> 1) and thought 'Whoa. I've never had a dream within dream before' and was telling my family about how I was telling them about a dream inside the dream I just had. Then I woke up for real (as far as I can tell lol).

Yes, but I don't remember it

I don't think so, not exactly, whenever I try to go to sleep in a dream I wake up immediately. Though one time I dreamt I was in a large empty train station on a bench and I woke up through like 17 levels in rapid succession.
