i just have some questions!

1) could you dream .. forever? --well, until u die lol
2) could you die in your dream?
3) when your dreaming, are you basically walking in your mind? i guess you can say
4) could you find things you never really thought about or just something very helpful, intelligent, or supportive INFORMATION, in your mind? like, say you go through a door and just expect something, that something that's in that door you opened, it could mean something right?
5) is it spritually speaking, "bad" to pratice or have lucid dreams?,
6) is it healthy for you in anyway? // or unhealthy for you in any way?
7) is there a way you can make a person have a dream about you ??..


THANK YOUU!
