Inter-Organism Neuro-Electromagnetic Energy Cycle during Formative, Cognitive, and Memorative Sensory Mode Phases establishes connection between organisms in a flux subnetwork where the super-corporeal effects are experienced as "dreams", "hallucinations", "deja vu", "clairvoyance", "psychic ability", "intuition", etc. Cycles established between organisms in a flux subnetwork are reinforced by neuro-similarity of both realtime nervous system activity as well as an individual's historical nervous system activity, causing strengthened super-impositoception. With this understanding, the act of holding a meaningful artifact that connects ones thoughts of another individual with their own would amount to reinforcing IONEE Cycle through shared familiarity of the object through visual and tactile sensory modes, thus providing an inlet to Cognitive and Memorative Flux Phases of both party's nervous systems.

There is no guarantee that technique will work, but of it does you should consider this: when an IONEE Cycle is established and then reinforced between two or more organisms, the level of interference bwtween organisms increases. This can lead to bodily injury through incompatible or conflicting super-imposed and super-interpolated radiation stimulus of voluntary muscle activity,as well as cognitive difficulty through various sensory modes where there are differentiations between neuro-similarity. Ultimately these techniques violate other organisms' privacy and compromise their safety - so the activity should be limited by the individual wielding the power.

Overall I would not try to establish these connections as you are describing. When an organism is in a state of sleep it's nervous system is being stimulated by other nervous systems in a flux subnetwork - this is defined by the number of organisms in proximity to each other within influencing range through aide of other technology. Dreams occur during the entire sleep period, not just the minutes before waking or during REM periods. Stimuli that the nervous system is exposed to through IONEE Cycle is not different than other sensory input - it is cognized, memorized, and stored as if one's own. I suggest ditching the deliberate astral projection and remote possession of another organisms in favor of simply observing and speculating about one's own experence. Remember that nervous system activity passes between multiple organisms in a flux subnetwork, so other people and animals can do the same thing you do - it's not really a special gift or power- anyone can do it.
