Yes, I'm very sensitive to spirits also. Have you tried talking to them about this? They are trying to get your attention. If you feel it is bad energy or spirit you may want to look into cleansing th your home if that's where you hear them. You will have to get somewhat comfortable knowing you have this gift And then you have to ask yourself "are they bothering anything or trying to harm you or anyone else. The ones around me has a fascination with opening and closing doors. They have a reason for being here, either to send a message though you or you may remind them of a love one. Do you feel like their bad?
