This is entirely true, it happened to my step Mom about 4 years ago. There was a day she awoke with a terrible pain, she couldn't move her legs for the entire day and the next day also. We tried several medications but nothing worked, we tried taking her to the hospital, she spent several days there but still there wasn't any progress after all the x-rays, scans and so on.
And then later On she had a dream, a beautiful fair lady dressed in a white gown with a long hair was sitting beside the door to her room, she stretched her legs when my step mom came to pass and she accidentally stepped on the lady's leg. She then shouted at her, the conversation went this way,
Lady- "Heyy! (being rude) Are you blind?"
Step mum- "Servant of Allah (the way to address a strange person in our tribe), I'm very sorry, it wasn't intentional. I didn't notice"
Lady- "This happened weeks back, and this is why I decided to punish you because you didn't apologies and I thought it was deliberate. Go now..."
Step mum- "I'm very sorry"
Lady- She shouted "I heard you, I said go!"
When she woke up the next morning, all the pain went away. She was able to walk again.
Second story, it happened to my step mum again. She normally sleep with a glass of water beside her, because she frequently wakes up one or two times to drink water and then go back to sleep. That's a normal thing that happens to her often. And then one day she got carried away and went to bed without fetching the glass of water. She woke up around 1am and realized that there was nothing next to her and she was so tasty she couldn't go back to sleep.
So she decided to walk to the kitchen to fetch a bottle of cold water from the fridge, she felt there was no need to wake my dad up. So she went and grabbed the bottle, but she felt the presence of something she couldn't describe. So she wanted to get everything over with in a haste and head back to the room. As she was drinking the water, she heard a voice saying "Sannun ki" (Hello dear, in hausa language). She turned around and there was no one there. She dropped the bottle out of fear and ran back to the room, she woke my dad up. He went down there to check and there was still nothing there.
There isn't enough time for me to share all her experiences, but here is the last one. At around 5pm she had a visitor and they were having a conversation when my younger step sister khamila (age 10) passed by her to go to the spare toilet outside the house through the back door. And she asked her upon all the toilets within the house why must she choose to use the one outside at this odd hour. Islamicaly it is encourage to lock all children indoors, and make the females cover their head as magrib (6pm to 7pm) approaches because that's one of the times that the jinns are most active. Khamila said she felt more comfortable there. To avoid argument in the presence of the guest, she allowed her.
The visitor left and there was no sign of khamila for like 30 minutes So she went to check up on her, she didn't want to open the door to respect her privacy. So she called her name, no one answered. She shouted her name for the second time, "khamila!" and she heard khamila's voice saying "sorry, i'm not through yet". My step mum then said "Be fast then, Its already magrib time". The voice replied "Tohm" (okay in hausa language). After like 5mins khamila was still inside, My step mum shouted again "I said come out young woman!", The voice replied once again "Naji de" (I heard you). My step mum had enough of it so she decided to open the door, Guess what? There was no one in there. She ran back to the house and she saw khamila on the sofa watching her favourite show called Sofia on disney channel if memory serves. She asked her how did she get in, khamila said she didn't even spend morethan 5mins out there, she passed while she was still conversing with the guest earlier but my mom didn't notice.
I might share more with you guys as time goes on.
