Seeing little wetness after a wet dream

Q:

1. When I start sleeping then in the beginning I don't sleep completely and some sexual things flash in my mind and some mazi comes out so this would be counted as wet dream? I am sure that I didn't have any vaginal throbbing nor did my heart beat get fast, so do I have to make ghusl?

2. When I woke up then I remember having a wet dream but there was no wetness nor mani or mazi but there was very little spot on my clothes which was looking like regular white discharge, so should I make ghusl?

Applying for faskh

Q: I want to ask a question on behalf my mum, who seeks to annul her marriage to my father. He refuses talaq, yet he does not support her and he lives in another town, he does not support me or my sister, but that is not the main issue, my mum is his second wife. His first wife passed away recently. He does not contact my mum but he does to come to 'visit', and he stays at his other sons house, and not by mum. For no apparent reason.
