Impurities on clothing and furniture

Urine coming out while sleeping

Q: I felt like my urine came out in my sleep. I touched my pants by hand but couldn't judge. I was feeling some dampness. I then touched the pillow and the blanket to get up and when I checked my underwear was slightly wet. I'm assuming it to be urine. I cleaned the phone etc as I touched it after touching my pants. What do I do about the pillow blanket etc. Are they impure as well. I didn't see any wetness but after touching my pants I touched the blanket and pillow.

Removing impurity from the door

Q: If there is visible impurity from along time ago and was never cleaned what should I do? And how would I clean it since its on a closet door because I can't pour water on the doors. Also if I use a soaking wet tissue, if the water while wiping falls on the carpet will the carpet become napaak? I avoid those areas of impurities so after I do wudo and close the door where the impurity isn't there will I become napak? I have read namaz many times before after doing so, did they not count?

Wet dream

Q: If I am not sure if I had a wet dream while I was a wake and had my period, am I impure? And if I go to sleep and use my blanket and sit in my house are those places napaak?

Doubting if one is paak

Q: If I am not sure if I am sexually napaak and I have my periods and if I shower not for paaki but just a shower, will everything I touch become napaak and since my hair will be wet after showering if any drops fall will they make things in the house napaak and since I have school and wear my coat and bag will they become napaak also? Since I can't wash that what should I do? And has my bed and every other place before showering become napaak now?

Reading inappropriate literature

Q: I was reading a text that was inappropriate not intentionally and it wasn't descriptive at all it just had an inappropriate word (sexual). Since I read it am I napaak now? and am I that type of napaak even if I have my periods? If I have sat on many places are those napaak now as well? Please help. This has been bothering me since the morning when I had read it.

Living in a hostel

Q:

1. I live in a hostel and I have to share bathrooms with kaafirs. My question is I have doubts about the purity of the bucket but I don't see any kind of visible najaasat. What I used to do was I fill up the bucket till the water overflow and I use the water from that bucket without throwing it and recently I have seen on this website that you have to throw the water to make that bucket pure. So was I impure all the time and do I have to repeat my prayers.

2. My room mate uses anti anti-perspirants like powder and I see particles on the floor and I don't know whether that powder is made from halaal sources or not. My leg touches those particles which is very much less than a dirham even after combining all the particles. Does my leg become impure and the places where I keep my feet also became impure? It was less than a dirham size.
