Can you condense this into laymans terms: SCP-5956 is the REISNO Cannon, a temporal manipulation mechanism allowing the synchronization of one's consciousness at two distinct points in time. When activated, the REISNO Cannon links the user's present consciousness with their consciousness at a chosen point in the past; in effect, one's "canonical" knowledge and experience can be augmented via intertemporal communication and cooperation with other versions of oneself. SCP-5956 is not known to generate new timelines. Attempts to alter past events using the REISNO Cannon are virtually certain to cause temporal paradoxes, resulting in catastrophic timeline collapses. Instead, it is used solely to initiate causal loops which have already partially occurred. A known side-effect of the use of the REISNO Cannon is the inability of one's past self to recall interactions with one's future self. Once the link created by SCP-5956 is severed, one's past self is subject to an antimemetic phenomenon causing them to forget 'crossing their own timeline'. This is not by design; rather, the effect is believed to be a fundamental principle of intertemporal self-interaction. This principle naturally decreases the likelihood of potential paradoxes, as one's past self does not retain knowledge which might cause them to act unwisely in the absence of their future self's immediate supervision.
