I also believe. My husband and I built our house when we were early 20's and then had our first child. When she was 14 months old she died in her sleep of SIDS. immediately after we both started hearing things. Neither of us said anything to the other for fear of being thought crazy but eventually we couldn't keep it to ourselves and told each other what we had each heard.
finally we left the house late one night after something grabbed my foot while we were in bed.
we still live there today. I don't hear anything anymore but my husband has had strange things happen when he is home alone, such as the windows being closed after he opened them, etc.
I don't know what it was but I know it scares you STIFF!! It is not cool or interesting, it is terror.
That is such a sad story annelizly. I am so sorry for your loss. I will pray for you, your husband and also for both of your protection.
