Voices

This is my first forum, there will be most likely grammatical errors or maybe some ambiguity and for that reason I am advising now that if there is any questions that need to be asked, do not hesitate. Please help to improve for a 'next time' and do not criticize me . I had a dream that warned me about my sister, I do not remember what the voice said, but it was of a man's voice. This was towards the end of the dream. Beforehand I was with my friend <PERSON>, hanging out with him not knowing what the reason or what exactly we were doing, the voice was warning me in the background constantly. I remember the end of my dream almost exactly, which was me in the minivan of my friend <PERSON> with her mom driving us, who knows where. Then I begin to hear the voice again in the background about my sister and then everything freezes in the minivan. I then decide to look in my hand and then I count 6 fingers, with the little knowledge I have of lucid dreaming I was able to discern that I was dreaming. After this realization I try to take control of the dream as well as the characters in my dream, such as my friend <PERSON> and his mother. I begin to breathe extremely heavily and trying to take control and keep peace of mind because that would have been the only way to take control of the dream, according to my knowledge. Seconds later I feel a strong pull from behind and I was still trying to take control by calling out to my friend <PERSON> and ordering him to help me since he was an object in my dream I can control. During this pulling I hear the voice constantly warning me about my sister. I should clarify that the voice said something like "check your sister" or maybe another synonym for check. In addition I have four sisters, and the voice did not specify to one but just stated sister, as a singular noun. Then after the entire shenanigans, I wake up frightened because I was scared of what or who the voice was as well as the warning itself. The warning was instilled in my head. This was during the middle of the night, then I went back to sleep not remembering what I dreamt afterwards. Now a bit of my background is that <PERSON>, currently, is my closest friend, I see him everyday in school and hang out after school. Out of my four sisters I only stay in touch constantly with one, lives in another state. The other three live in the same state and close, yet we do not stay in touch. I still receive news about my sisters whether from family or other types of media they use. If there is anything you need to know please ask. THANK YOU in advance!
