Since it's summer an' everyone's at th' pool or whatever it's been awhile since th' last question - an' at least this one's a good one! The short answer is, "you betcha." Yup, that's right, Lassie not only calls ever'one t' fetch stupid lil' Timmy outta the well, but also sees an' hears all your ancestors when they get t' talkin'. You already know that dogs, cats an' other critters have better eyesight an' hearing than we do - but y'know what one o' the biggest problems humans have with keepin' in touch across the planes? Logic.
T' tell the truth, lil' kids - an' especially babies - can see us too. Like animals they can't tell other people what they notice 'cause either they can't talk at all yet or they're just confused an' don't know how t' say it. Ever wonder why babies do that thing where they laugh at absolutely nothing or stare off at somethin' nobody can see? They're so young that they don't reason themselves into a corner an' block off their connection. Sounds like a lotta mumbo-jumbo, sure, but it's true.
When you see somethin' outta the corner of your eye but nothin's there when you look dead on, you start sayin', "I'm probably just tired" or "musta been my imagination" or some other BS like that. Never mind that yer peripheral vision is faster than yer foveal vision (lookin' directly at somethin'). An' sometimes you feel or hear somethin', right, an' freak yourself out. Sometimes when you jus' lost somebody you love you think yer mind's jus' playin' a trick on you - that you just imagined it because you wanted to hear or feel it, right? Think again. There's weirder shit out there that we can't explain - spirits are the least o' those.
I guess what I'm sayin' is t' pay attention t' Lassie when she's tryin' t' tell you somethin', an' don't automatically rule out that someone you can't see is stoppin' in for a visit. If I could tell my wife an' kids that, I'd feel a helluva lot better m'self. Do everyone a favor an' spread the word.
