What could this experience mean? Pregnancy and the paranormal?

I've had a lot of experiences over my life time and I'm a believer in this phenomena.I've had experiences where I lived in two homes where the people had committed suicide,I've also been visited by two family members that have ped on and I also had an encounter with a negative shadow figure in a friends home.What could be possibly happening is that you have a spirit in the home,it could be connected to the land that your home is on.Animals are highly perceptive to any type of spiritual activity and they will alert you to this.I've had both cats and dogs that have alerted me.I don't think it has to do with you being pregnant at all.This is what I suggest that you do,you can check out your local historical society and see what was on the land at one time.You can also try to communicate to set your mind at ease,grab a digital tape recorder and run it and ask some questions,such is there a spirit present,what is your name and why are you here,play back the tape and see if you have any intelligent responses to your questions that you have asked.This is how paranormal investigators try to debunk or doent of their findings.When a spirit manifests it's self,the room will drop in temperature and you will experience cold spots,they manifest from any type of electromagnetic field,such as appliances,lights or TVS.Try not to be afraid because they will feed off of your fear.Now what you can do to bring you some peace of mind is to burn some sage in your home,this can be the kind that you find in your grocery store spice isle,this is how people cleanse their homes of negative energies or any spirits.This is known as smudging.If you choose to do this,you must burn this in each and every room of the home and command the presence to leave in Jesus Christ's name,tell it that it is no longer welcomed in the home and you are banishing it for good.Give this a try and see if this doesn't help you out,if you need any further istance,I'm in this section each and every day and will be happy to help you out.Tomb Raider.
