When I first moved to my home we blessed the house because we believe there was a spirit that would shut off the TV , Shower and so forth. My sister and I actually felt the presence touch us inapproriately ( only once each of us about a year apart).
It has been about 3 years since we did this. Last week I thought a lot about death and my family if I did die how my family would feel. I wrote a letter saying goodbye to my family and said something small to each one of them (mom dad, sister , etc... )
The same night I dreamed my husband and I were in a coffin under the ground and he was talking up a storm while I was trying to keep him quiet so he would not take up all the air because someone was going to find us.
Anyway the next day and a couple of days later I notice the room I was in all of a sudden got a funky rotten egg almost type of smell. Could this be something or am I concerned for nothing?
It was not gas LOL

Spirits can come and go, if you have previously had the house blessed, perhaps you should again

Why does a spirit smell like a rotten egg or so?
Never heard of that !

Might want to have your house inspected for methane gas.
This carries no odor, but is found in sewer gasses, it can be deadly, it is flammible, and can cause some strange health hazards. Including changing of mood and how we think.

Sewer gasses are common in homes, just see the plumbing board.

I recently working on my sewer line all day, hovering over the pipes for 10 straight hours. Later I became very irritable, depressed, and just had a drained feeling. I snapped at everyone.

I researched this on the internet and found that these are all symptons of over-exposure to methane gas.

Modern TV's can be shut off if there is a lot of interference in the room. Ive had that happen before.

A shower cutting off could be just something as simple as debris in the showe head or valves, or poor water pressure and someone does something like flush a toilet or fill the washer.

Having the weird dreams, may again be a sympton of methane gas, mold, mildew, etc. Just stuff to consider.
