something tells me (that)
I have a strong belief, suspicion, or intuition that (something will happen or prove true). I'm going to have work the morning after my birthday party. Something tells me I'll be calling in sick that day! After the fight we put up, something tells me they won't come back to bother us again anytime soon.
something tells me
I suspect, I have an intuition, as in Something tells me that she's not really as ill as she says, or Something told him that it was going to snow.
