my husband saw a blue light?

Sign of a good spirit or angel.....that looks over you and the children.

What you described sounds like auras, sort of a color we all have that surrounds us. Your husband might be a person who can see these auras.

Shadow people go away if you ignore them.

Sometimes when you turn the heat on a air conditioner after it hasn't been used for awhile, you get a odd hair burning smell. If it continues ,just to be safe do have it checked.

The phone number sounds more technological than paranormal, ask the phone company.

I cant swear to it but a very spiritual mystic woman was asked

a similar question and she answered that such things are the work

of mischievous spirits.The same goes for flying saucers.

Maybe your husband should get his eyes checked, seeing lights that aren't there can be a symptom of serious problems.

You might want to get an electrician out to check your air conditioner too before your house catches on fire.

The phone call is not related.

You're being haunted by the ghost of the English language. It has come back for revenge.
