Hello. This is my first post. I am happy to be here and sorry if my english isn't fluent

Back in school I made a wish to find the truth and to see my abilities, powers. My meditation object - math. I solved math everywhere and at every moment. At some point i was identifying myself as a pure will. One day, i was thinking about one math problem and just before lesson a voice said: "today is the best day in your life". I am quite sure that this voice was not mine. I noted(i don't know myself) and continued to solve, but couldn't find the answer. So I asked myself how i can solve it? And the answer was: try to solve it with your entire being. Still i coudn't find the answer and gave up, but then it came to me: "I am not a thought". As my eyes were open I saw my friends chatting, but were were no sound at all. I closed my eyes and came to emptiness. That voice said: "there is nothing here". When i made myself to go back to the world. As I opened my eyes in front of me were was something waving, after some seconds it faded. Then in the background i saw huge waves and somehow those waves and people were connected and everything pointed to one place. Far, very far away there is a place, i couldn't describe it by any word. I just knew that we all came from there and we will go there. But now I could not go there. Then my attention turned to my suroundings. At some point that voice asked: "What will you do if all your dreams come true?". I coudn't find an answer. But it came to me:"I will spread happiness". It was something i didn't know about myself. Then the voice knocked to the door(I understood it as:what about this?). Behind that door there was other personalized me. I just now realized that it is made of ignorance.I wanted to have that other me. After about a half a minute, there was something rising in me. It was energy. I somehow felt wise. I intuitively knew if i use that energy in that way then this will happen. Then I started to spread happiness

. At some point i got attached and carried away. It lasted for 45 minutes.
My question is? Who is that voice? Is this a stream entry?
Now i am starting to know more about buddism. In my practice(anapanasatti) i am sweating a lot, maybe there is some way to cope with this?
