Two months prior to my wedding, my younger brother, then 20, was killed in a car accident. It happened on a Sunday morning and we buried him the following Wednesday. It was over Labor Day weekend in the midwest. The following weekend, probably about the same time as my brother's death but one week later, I was at my fiance's watching tv. We had no air conditioning and the windows were open. I don't know if you know the midwest but September can be hotter than August and there was literally no movement of air, no breeze happening. It was hot! I was about to fall asleep when all of a sudden it got freezing in the room. I was really scared. I said to my future husband, "Do you feel that? What is it?" He said, "I think it's your brother." I was so scared (I have never been as scared in my life as I was then nor since), I held his hand tightly and shut my eyes. He looked at the end of the room and said, "You can move on now. I'll take care of your sister from now on." Suddenly, the cold ended as suddenly as it had begun. Strangely, the room was just as hot as it had been and there was no residual breeze or temperature change from the cold that had entered the room. It was like stepping into a meat locker and then coming back into a normal room.
Although other family members have since died, I have had no other "visits" like this and consider myself a fairly rational person. The concept of my brother coming to me as a ghost isn't really part of my Christian education regarding death. I am not a ghost hunter and would freak out if something like this happened again.
They say the young do not rest. I believe it was a visit. You should not be scared. When my dad died three years ago I had the smell of his pipe tobacco in my room also I had a smell steak on the BBQ in the middle of the night. I have not had a visit since in smell but he does pop up in my dreams as a young and health man. :) I ask him to visit me. I'm sorry about your brother :(
From author Dave Hunt:
"Man is a spirit living in a body through which he participates in physical events. The spirit in man distinguishes him from animals and makes it possible for him to know God. Neither man's body nor soul is in God's image, for God has neither. Man's spirit is in the image of God. Separation of man's spirit from God's Spirit brings spiritual death to man...
AT DEATH the body goes into the grave and 'the spirit shall return unto God who gave it' (Ecclessiastes 12:7). Taking the Bible as a whole, this can only mean that man's spirit is at God's disposal to be sent either to heaven or hell. The spirit of a dead person would not be floating about, haunting or appearing to those on earth, as the world of the occult would have us believe. 'Ghosts' can only be masquerading demons."
Any apparent communication from an alleged discarnate is taken as evidence [if believed] to support the serpent's lie that death is nothing to fear. Having 'proved' its identity, the alleged discarnate invariably proceeds to present...lies...that souls and spirits are free to flit about on the astral plane and have become communicators. One cannot believe in communication with the dead and at the same time believe in God's word:'...it is appointed unto men once to die, and after this the judgement' (Hebrews 9:27).

At the end of my post I mentioned having "more stories" about the house. One of them was very similar to what you described.
This time though it involved both of my brothers and a visitor we had sleeping over. We were all up late, since it was a Friday night. We were just talking when all of a sudden a red dot appeared on the floor. I was sure it was a reflection of some kind from one of the windows so I got off the bed and went to the first window. I flailed my arms and moved aroung the window but the red dot was not affected. I asked my brother, who was sitting next to the other window, to do the same. The red dot then began to, how do I say this, expand and retract. At the same time this was happening the room became extremely cold (and by the way, it was September in Oklahoma at this time, about 70 at one a.m.). The red "dot" became a glowing red pit and air rushed from the room to the "pit" and as soon as that happened it was gone. We all sat there in amazement. No one spoke of the incident outside of our circle for a very long time.
There are a few more, but I'll save them for later.
