I'm new to lucid dreaming but have done it before without noticing it was lucid

My first Dream was kind of realated to falling of cliffs an waking up befor hitting the ground, it started really clear ike could draw it now if i wanted it was so clear and rememberable i was in a gaint deserted ASDA ( supermaket )with my parents, this ASDA had a huge car park and the building was falling apart and mouldy ( not your usal ASDA) right beside it as a cliff as my parents went to go in the shop i pulled the hand brake
the car slowly rolled towards this cliff and fell (me still inside ) as it fell of it tipped in mid-air normally id wake up by now but some how a flash of light went past and i was in the car again with my parents driving home .........

Shortly aferwards i woke from this strange dream.
this happened about 3 years ago and i can still remember it
