Welcome to CH
1.can a djinn read my thoughts?
If you allow them to do so.
2.how can a person get privacy like looking at something you wouldn't want someone to see you watching or doing.
You will need to establish House Rules.
3.how long does it take to hear or see any form of a manifestation of your djinn
That is entirely up to the Djinn. Each Djinn spirit will be different and the types of manifestations they will use will also vary by each spirit. The level and types of manifestations will be developed through a bond of trust between you.
4.not djinn related but how long does it take for a level 4 spell or anything that is that level to work?
It depends entirely upon the spell and what is helping you to achieve.
5.can my djinn hear me if i talk to them?
Yes they can hear you whether you speak out loud or through your mind.
