Solaris and the date 9-18-2012

A little background before I move on to the dream I had. I got up this morning and wasn't feeling good, so decided not to go into work. I sat down at my computer and turned on a guided meditation to help myself settle and relax and heal myself. Afterwards I laid on the couch and went back to sleep.

Now for the dream..
I was in a strange, yet familiar house. I was sitting in a chair looking directly out the window. It was dark outside, but there was a shadowy figure that started to form on the outside of the window. I closed my eyes and the next thing I know my dad was coming in from the outside. I stood to go greet him but the moment I saw him I knew he wasn't him. I confronted him and the person pretending to my dad kept insisting that he was. I said "Okay, I'll prove your not him," and I picked up my cell phone and dialed his number. The phone on this mans belt did not ring. When he found out that he was caught he just disappeared. It was hard trying to convince the others in the house that there was a spirit among us. I could see a purplish wisp of smoke/fog floating here and there. It then lead to me a room where I had to open part of the wall, like a secret locker. I opened it and there was pictures and a letter I opened. Upon this letter, what I could remember so clearly reading was a word and a date. It read SOLARIS 2012 .. and the date was 9-18-2012. I tried reading the rest, but for some reason it was blurry and I couldn't read it very well.

The next instant I woke up and wrote down the word and the date, in order to look it up later. It has lead to no where. Does anyone have any ideas?

Thanks for any suggestions,
Love and Light,
Serenity
