If you are referring to the spiritual realm, then don't look too hard. You aren't going to see this until.... Well, you die. You see our bodies are simply... windows into the physical realm [the realm you know now around you]. In a sense we are not technically physical beings. We just use our bodies until their time expires, then our choices [or rather a single choice] determines if our spirit or in our sense "soul" goes up or down.
When you see/run into your own spirit you are supposed to die.
spirit = πνεύμα [pnevma] (see pneumatic)
spirit = πνεύμα [pnevma] (see pneumatic)
The Holy Spirit (The Spirit of Promise, The Person of the Holy Spirit) See Matthew 3:16
If you see your mothers spirit on the day she died, she is trying to let you know she is okay.
You are hallucinating.
You see, if you wish for a spirit to let you see it, you either need it to be really angry at you - but I warn you to avoid that path - or gain its trust.- Cheshire Kat
