Assisting one another

Q: For rotating money in the business, one person will be collecting a fixed amount from the 10 persons for the 11 months (including himself). Each month he will gather the entire amount and for the first month he will take the entire amount himself. For the remaining months, whoevers turn its is will take whole collected amount and the first person will take a small amount of commission (fixed amount) as the maintenance charge of this system. Is this system allowed in Islam? Is the commission amount interest?

Dream

Q: I saw a dream and I am really scared. Almost everyday I get these types of dreams. I saw an old woman praying on a prayer mat and asking for money. I went to give her money and she said that you are in pain right? I said yes, then she took a name of my uncle and said something. I asked her am I going to die? She said yes and that also in 2 days. I went home crying and I was sitting and making dua to Allah. The same woman came to me and I was crying and saying to her dua can change anything and she also starting making dua and I was looking at the sun it was full round and orange color and making dua the woman starting laughing.
