Curious spirit?

I just had an experience last night. I was just dozing off when I saw two, abnormally tall men standing at the foot of my husband's side of the bed. One had blondish white hair and wore a beige, white and brown plaid shirt; I only glimpsed the other, shorter man. I made a surprised sound and they slowly, very slowly faded away. I finally got to sleep, but it really freaked me out.
I have only have a FEW glimpses of apparitions. The one threw me as i was alone in our shop early in the morning as i was loading my truck for day. Out of the corner of my eye i know i saw someone walk over to one section where we stored our electrical breakers. Yeah i jumped lol.
