1.) yes you can drive a lamborghini (my personal favorite is diablo !!!! )

for the first time you become lucid, just try to calm yourself down.. just let everything settle in without you going all insane and getting too excited. Excitement will wake you up prematurely and your LD will only last but a few seconds..

After you think you have calmed yourself down and everything has settled in.. try something small, like moving an object with telekinesis (i love doing that) after you get more experience and better stability, you can progress to better and harder things!

any other questions, feel free to PM me
