What you dream about is not your soul, but your usually neglected and repressed personality.
The wardrobe represents your subconscious, or your heart.
Suicide means that you give up your subjective personality and suppress yourself. Death in a dream means depression.
Under normal circumstances, the main personality will suppress the sub-personality, so the sub-personality will usually be suppressed in the deep heart, which is why there is such a saying as "worrying about the sky."
Since your main personality is self-suppressed, your secondary personality will naturally come out.
Yage went back and couldn't find her body. Maybe the two personalities have merged into one. But I'm not sure.
I suggest you see a psychiatrist as soon as possible and let the doctor help you. You must have been hit hard in reality, which will make the main personality suppress itself and give up. Professional doctors will help you get through it, otherwise this state will last too long, and I am afraid there will be unpredictable consequences.
