Can We Possibly Do This?

[WalahKaja]

Hello everyone im new here, so im not know i should put this on Biology or Computer Science, because what i mean is a machine for this. But i want to ask can this be possible first.

1. Can we send a image or video to your brain directly even if your eyes closed?
2. Can we shutdown our body except our head and we can still think, talk, and hear ( so anything below neck will can't move even if possibly i want the neck not move ) without drug / medicine?
2,1. Can we make someone get sleep paralysis of course without drug? (  Its just if the second question is impossible and i think its more impossible i though ).

Sry if you think my question feel like im crazy, i just want to know.

sry for bad english because english is not my native language.
