Question concerning an aparition

Hi there, I am new to this forum. Thankyou all for having me. I am curious if someone can be unaware that they are astral travelling. But can be spotted by other more enlightened people. The graveyard shift employees at our bakery for years now have seen an aparition looking very much like my husband, walking around at night, working in the office and standing near them watching while they try to keep working. My husband thinks the whole thing is silly. He also has sleepapnea and wears a cpap to sleep. The instances that they have seen his apparition at night have been less since he has been sleeping better. Thankyou for any thoughts on this.

Two suggestions:

1) Tell the employees to talk to that apparition and see what happens. Then, ask your husband if he remembers anything in the dream.

2) Have your husband stay up one night and see if that apparition appears. If that apparition appears, then maybe it isn't him, because he was awake during that time.

Tell us how this turns out.
