Dream Of Underwater Rescue Mission

we were forced to go underwater as punishment for something, and there was this modern looking house that i went in and was looking for something. i think i was trying to save my kid. anyways they told me he had died and his body was tossed into the deep blue, so i broke the window and swam out. someone that was with me yelled “HES NOT OUT THERE! THEYRE LYING!”. and this huge dragon looking monster came out of a hole causing the whole house to shake. they wanted me to play a game of volleyball to get my son back. i had a gut feeling this was the thing that took my son from me, there was 2 of them against me. so i took the volleyball, jumped up, and slam dunked the 1st one, and the second one while i was still floating in the water, i charged at him with my elbow and dunked him as well. i remember water flooding into the house from me breaking the window, and everyone was trying to get into the elevator to save themselves. i was shoved in at one point by my partner in the dream, and they said they would go find my son, but i opened the elevator and insisted i go find him.
