I'm unsure about my lucid dream last night as i think it was my first ever as i had just woken up form another dream where i just checked whether i was dreaming by trying to breath under water although i realised i was dreaming i woke up straight away and when i went back to sleep i got in a dream and this dream confused me

You see i was creating things in my dreams like a fencing as if i was setting up a place to live for me and my family but i wasn't all there as after that i tried to make a water slide for some unknown reason as if i wasn't in control but i was as i was making all these objects appear and then i thought to myself when am i going to telll my family that we cant live here as if its a dream but the question i havve is if i kneew it was a dream why was i treating them like real people when theres just DC's? and also why was i doing stupid stuff like creating a water slide?

but on another note i can remember pretending to swim and ending up flying but i realy need some help as to whether i was actually lucid i not im very unsure?
