So, sometimes I'll have a dream and then it happens. Usually its meaningless things, like my brother getting me a bowl of popcorn. Other times, it's some scary stuff. For example, the day my mother died (October 22nd, 3 years ago) I had woken up from a dream where she died. Then last night, I had a dream that my father had an accident and was going to die. Is this just because Oct 22nd is approaching, or should I be worried?
This isn't unusual, lots of people have precognitive dreams. I wish I could give you advice beyond that, but I can't. This is your life, your dreams, your business. Only you can decide what you need to do.
Follow what your instincts are telling you. If you think it is just because of the day, then do not say anything. Though if you feel, deep down, that you think that will happen, then warn your father. Do not freak out and make it seem like you are crazy but just keep him at home. I know for a fact that dreams can come true because I once had a dream that my missing cats came home and were playing with me on the living room floor. The next day they had returned home and they were in the exact place they were in my dream. Listen to your heart and don't give up.
I get dreams like that that happen all the time. like strong emotional happenings that happen in everyday life, i will sometimes have dreams about before they happen. I tried to explain it to my elementary school teacher once (considering i have been able to do this for a while) and all she called it was deja vu. however, i knew that this wasnt the case. i could predict friends break-ups and time when their relatives die. but the problem with this is that i could not control it. it just happened at random.
i wouldnt be too worried about it. but id keep a close eye on him.
