I have run varying tests in consciousness to disprove this and have failed every time. There are no individuals, there are no separate experiences, reality is just a mass hallucination to create an illusion of other. It's very well done, so masterfully done that if you attempt to destroy it, it will actually turn against you. It's weird, you both do and don't want to break the illusion of other and it is this resistance that creates the Dark Night of the Soul, or suffering involved as you break through every illusionary identity that you keep constructing. Finding out absolutely that any notion of other is just pure imagination is a bitter pill. While I do absolutely love myself, and I do love others it is actually so self-evident that it actually would be impossible for others to actually exist outside of you it reveals why both Infinity of Gods awakening Leo had is both true and untrue. It's true you could imagine that possibility, but that possibility is within your own awareness which means by default, it was never separate from you to begin with. People would say but how do I know someone doesn't have experiences outside of me, well they on the absolute level cannot, but you can imagine they do....and thus on the relative level they do. But all relativity is imaginary, there is only one being. Anyone that tells you otherwise is just a plant you created to protect yourself from waking up. You might ask why would I do that? Easy!!! Because when you are fully ready to awaken....your deception cannot deceive you. You need to put people and events in your dream to bind you as a buffer to keep you asleep until you are ready to awaken. When you are ready to awaken, no deception can fool you, and you will venture forth dissolving all illusions/deceptions into the absolute truth of ONENESS.  It's a bitter pill if you are too attached to the concept of other.
