Modifications have been made;
-I've always had a problem with understanding grammar (thank you British Public schooling system!) I'm going through it with a more attentive eye, so forgive mistakes for now.
-Added some back story so the SCP is now in possession of the house, let me know if this seems like it's too harsh/not harsh enough for the SCP
-Changed Containment Procedures, keeping the curtains and door open is now a means of additional security, not a basic procedure.
-I now have a point I'm heading towards! This was the hardest but most fun issue to tackle:
The property was built as one large house, a means for the original owner to have room to out pour his fears and memories, the internal space matched the anomalous space and sleeping was simply a means to let these fears and memories escape. The property was then divided into two semi-detached houses, the house on the right remained quite open, no additional internal walls were built though the internal space was slightly smaller than the anomalous space, it may cause a sleeper to be a little restless but otherwise it was not harmful. The house in which SCP-XXX is located continuously had internal modifications made, the most recent occurring just before the nightmares began, because the internal space has been so confined, the anomalous space has become far wider and easier to hide from, however, emptying the room of furnishings decreases the anomalous space to the point at which the old fears can find the subject.
Or to put it simply: The lower internal space, the greater anomalous space. Anomalous space contains the memories and fears of the original property builder, the larger the space, the less likely these aspects are to be encountered.
It's a little raw, but that's the sub-plot I'm trying to work in.
Thanks in advance.
