Is it normal having a cockroach/betal in my dream 2 time ?

So, from some days i am limiting my smoking habit and have been eating bhang ( cannabis extract or plant material rolled in a ball which you eat and get high but in the mind) so with me anytime i intake weed it cause me to break out of addictions and people and i get grumpy. and last day i got high in my feelings and focus which made me get angry cuz i notice more and for also i listen to the doors which have many sublime meanings to it.

(TO the DREAM)
so i slept at today night at 4 am and i was really tired was playing game and i dreamed about my house it had 2 kids who were sibling of the 1 gurl standing in my house and after some time they got away of my house and i found a beautiful blue cockroach/beatle size of 5 inch at first it ddnt do anything and then it started to fly really close to my right hand but it ddnt bit me it had big fangs though and i got scared and woke up like crazy.

Btw i got this dream before but in that it was shorter and i ignored the cockroach

( real life scean)
back some days i tried to help a blue eyed carpenter beatle it had mud on his wings and i tried to help em by pouring water but i kinda throw em in woods cuz i was busy.
