SCP-3883, aka, Dildos Have Dreams Too is a Safe-Class anomalous object. It is green tentacle-shaped silicone dildo measuring 16.5 cm in length. Two anomalous properties are associated with SCP-3883: the first effect manifests when SCP-3883 is placed in front of a reflective surface, while the second effect manifests when a human individual enters REM sleep within a 1.5 meter radius of the object.

When SCP-3883 is placed in front of a reflective surface, the resulting reflection will differ in appearance from SCP-3883, depending on the type of reflective surface used to view the object. Ranging from, a tentacle dildo, a green octopus, a being that resembles a humanoid resembling a mindflayer. a creature that resembles a gazer, and an organism resembling a sea star.

When a human enters the REM sleep phase while within 1.5 meters of SCP-3883, they will enter a mental state involving highly-realistic dreams7. The affected individual will be unable to leave this mental state by their own will; to return to full consciousness, they must either experience a "death" within the dream or be woken up by an outside force. SCP-3883 can only affect one individual at a time.

Dreams reported by individuals affected by SCP-3883 are varied in detail, but possess repeating themes. All SCP-3883 experimentation subjects report being chased by an antagonistic entity, designated SCP-3883-1. SCP-3883-1 has been noted to appear under multiple guises, but tends to be described as a large figure (standing over 10 meters tall), possessing multiple appendages and colored a bright green similar to SCP-3883 in hue. SCP-3883-1 has demonstrated signs of sapience, and based on collected data it is currently theorized that SCP-3883-1 is an alternate manifestation of SCP-3883.

Communication can be established with SCP-3883-1 by a sleeping individual simply speaking to it during a dream. When engaged in conversation, SCP-3883-1 has exhibited differing demeanors with members of Foundation personnel it has interacted with.

Upon successfully interviewing SCP-3883-1, it confided that the reason why it traps people in nightmares with it as the antagonist, is because it is aware that it in the real world it is a disembodied tentacle. It believes that tentacles are supposed to be attached to eldritch abominations or an aquatic monster and be used as a "mating substitute". Hence why it lives out its desire of terrorizing people in the form of dreams. He finds the truth of his existence to be extremely embarrassing and being able to live out its dreams in the minds of others is the only effective way for it to cope.
