I've only had a few lucids, but here goes.
1) They were probably lucid dreams, especially if you realized it (Though I've done reality checks in dreams that were succesful, and I just kept dreaming LOL)
2) Try lying on the bed for a few minutes, or singing a song (works sometimes for me ). It gets better with practice.
3) Not sure about that one :/
4) Try imagining yourself floating thrugh the window or ceiling. If you DO have a window, you could break it and jump to the ground. Either you will wake up or you will land safely and continue your lucid.
5) Try rubbing your hands together (The friction that you feel will calm you and make the dream more stable) You can also try breathing deeply.
6) Almost everyone can lucid dream. If you did it by accident you can do it purposefully As for you heading straight for bed, either forcefully will yourself to stay awake, or put something near your bed that will remind you not to go back to bed (It should be there in the dream)
As I said, I've only had a few lucids, but with my small experience and from reading other people's posts, this is what I've gathered
