Gory Dream....what doyou think???

Ok. We just moved into a new apt w/ no basement, 2 bdrm. The previous tenant killed himself. (though we were told it did not happen in the apt). Just had a dream g/f and I were talking in the basement, then I noticed shadows up the stairs, like that of a large tree. A strange, blood curlding noise, that caused me to nealry faint (my g/f held me up) and then my eyes started rolling back into my head and blood began to run from my ears, my head was throbbing. we started running out of the building and i then noticed the shadows had turned to skulls. then i ran out. the noise was in the basement. it was very vivid, real, sounding....
