Impurities on clothing and furniture

Q: If there is impurity on a pillow and if I wash it in the washing machine, will it become pure?

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.

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?

Q: I have some soap stuck on my ring after I used the washroom and washed my hands. I have gone about and done household chores and cleaned places etc. Are my hands impure as I saw later that soap was stuck on my ring?

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?

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?

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.

Q: I gave my impure clothes to the laundry for washing and asked them to wash and press. I'm now doubting that what if they have not washed and instead dry cleaned it and they misunderstood me though I gave it for washing.

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.

Q: If someone has touched a door with impure hands, will wiping the door with wet tissues be enough followed by dry tissues. Do I have to wipe three times or once will be enough?
