There is A LOT of ambiguity around the term “Spirit Guide” and it needs to be clarified because many people are getting absolutely confused by it.
On the other side of the veil, there are many different realms and can be considered to be the “Ultimate Reality”. One of these realms is one specifically that deals with incarnates on Earth. It is the realm closest to the veil and it looks a lot like our planet for obvious reasons.
This realm is referred to as the “Spirit Guide” realm as it is where Spirit Guides who live the physical incarnation with their incarnate. There is a unique bond shared with each Incarnate & Spirit Guide where the Spirit Guide will share the emotions, thoughts and feelings of the incarnate. They are one with you but you do not need to worry about what they feel because their awareness is so much so that they know how to deal with them and they use it to help guide you to the next experience/opportunity/phase in life.
