Let us make it clear, asking our Father for a sign is not evil, unless that sign is to prove He exists. This is evil in the eyes of God, one must first have faith in order to recieve a sign, if you are asking for a sign to prove He is real, then it is not asked in faith. Many examples in the Bible where signs are good. What father would not be proud to give advice to their children who ask them for direction in their lives. Therefore our Father also will be more then happy to give us signs, if they are asked in sincerety, and asked specifically for directions from Him.

About your incident, about being paralized, at this point is when the flesh is most suseptible to demon possesion. you did well in thinking of Christ when this occured, and you shall be blessed for such thinking. Now of coarse science will come up with another name for it, like they always do, in things they do not understand in the spiritual ways. Can't be demon possesion therefore it must be a sleep disorder of some kind, though rare still a sleep disorder. bah hum-bug. In almost every case of an actual demon possesion, this what happened to you has been reported to happening to them. Thinking of Christ is the answer to ward off such demons.

Demons need a place to dwell, no matter what, it has to be flesh, even an animal, however they have much more control and freedoms if they dwell in human flesh, in order for them to enter into a human flesh, many requirements must be met first, set up by God Himself, the mind is not to be affected during such times as a demon trying to enter into the flesh, if then that mind accepts the demon, and the body is without movement, can a demon enter into that flesh, But as long as the mind is active, and can think on Christ, the demon cannot enter, he does not have permission to enter such a one. Also be aware of this. if a flesh already has a demon in them, that demon can invite other demons with him.
Anyway, you did well in thinking on Christ.
