Meaningful or just useless dream? help plz?

i dreamt this all in a time span of 45 minutes, and it took like 2 minutes in teh dream. first of all i woke up at 9 and just went back to sleep cause i was tired. now the dreaming starts.ok so i dream that my friend is at my house in the day, and he goes to use the bathroom. we were in my bedroom with the A/C on at 16 degrees Celsius. A moment after he closes the door, the power goes out (this always happens in teh country i live in, we are on a shortage of power so we have schedules and backup generators) and its pitch black and my friend wasn't making any recognition or noise. i couldnt see **** and the wooden rafters on my windows closed with the outage of power without me noticing. the wierd part is that my AC was still on for a few seconds and i was staring at it scared as hell, btw my door was open so that really doesnt make it better. then the power came back and then when out again and this time the AC and Wifi internet modem were both on and not turning off due to lack of power. i decided to lie down and wait for my friend, but then i suddenly woke up and there was power and it was at night and my friend was no where to be seen. i guessed that he might have left because i fell asleep. i sprinted for my mothers room, obviously she should be home at this hour, and it was to find her room dark and empty with the blankets a little untidy (i mean someone had been there). then i went to my sisters room and at first glance it was empty but then i looked again (the light was dim) and i saw my sister sleeping on my bed with all her stuffed toys gone(shes 12) and my mom sleeping on my maid's bed (she sleeps in that room) WITH ANOTHER OF THE SAME SISTER. i was scared to hell seeing 2 of the same sister so i shook my mom awake and said "MOM WAKE UP THERE ARE 2 (sisters name)'S! she left half her body, looks at them both, and just goes back to sleep. then i ask her where the maid is (i used her name) and she said that she just woke up. then i woke up. wierd, huh? i didnt wake up panting or heart beating fast or anything i was just glad to be rid of that dream and be able to see clearly as it was 9:45 am. my maid is fine and my sister is fine, and my mom is at work(preschool)
