I had a team member come around last night and we looked at ghost evidence which had accumulated. During an EVP session in a guests attic bedroom we asked the spirit to speak into my audio recorder. When we played the audio we heard my Gauss meter crackling as it detected electrical energy. Over the top of this there was a breathe and what sounds like "See You". We looped it over to keep hearing it and it's fascinating. I remember clearly that the four of us were quiet for this session, obviously. 

I downloaded an IPad app which records you in your sleep. When it hears something it makes a sound recording with time and date. I taught me that I go to the toilet a lot through the night. 
I don't snore though so that's something. I can use this app for catching noises in a locked off room while investigating. Quite exciting, for me.
