what to do in lucid dreams?

right i almost never get LDS and afte watching inception about a week ago i had a lucid dream it was quite along one but i didn't really know what to do with it but i will get to that in a bit.

right so im non lucid its start of the dream and aparently its xmas morning im on 14 and for some reason my family and i are driving round in our pyjamas for some reason and after a while i say to myself something is not right hear then i instantly became lucid and i was like F""K YEH lol `and at first i wanted to look at the detail of the dream (thats always intrested me ) so i look at the dash board and i was amazed at the detail it was like real life and then i said to someone sitting next to me WE ARE IN A MOTHER F**KING DREAM! and he turns to me and says what and looks at me like i am stupid but i was so afraid of losing the dream (becasue i hadn't had on in about 4 months) i just said to him never mind but i was intimidated by him and i knew if he started fighting with me or something adrenalin might kick in and wake me up so i got out of the car and i didnt realy know what to do i had tried to fly ages ago and it didnt work so i just wondered around and i didnt want to do anything that exciting and i cant do the spawn thing there were no cars around and when i saw someone the dream started to fade but i had to keep saying this is a dream to stay lucid and after that i cant remember what happened.

so have you got any tips of what to do in a dream ?

do exciting things.
Forget the adrenaline, you'll get used to it the more you try.
And use passive techniques as opposed to active, they're still cool.

e.g. door -> summon person (passive control)
as opposed to e.g. click fingers -> summon person (active control)

passive is for beginners.
Let your imagination run wild, that's what you do in an LD
