Yeah a lot of the Benadryl memes out there are about dementia.

No, Benadryl has not been (directly) linked to dementia, but it is classified as an anticholinergic drug, and those HAVE been linked to dementia. So not Benadryl, but the group it is classified under. That group of drugs also includes some extremely powerful antipsychotic medications (EDIT: sorry, anticholinergic drugs are often prescribed along side antipsychotic medications), so it's kinda like lumping a Nerf gun in with assault rifles. As well, sleep deprivation has also been linked to dementia and people will take Benadryl as a sleep aid (as you know), so any connection there might be ancillary. Your doctor's advice sounds like it is just precautionary, which is good, but may turn out to be unfounded. Bottom line is that it needs to be studied more as there currently isn't enough solid data about the subject.

It's crazy because zzzquil uses diphenhydramine as its active ingredient and you wouldn't know it unless you read the bottle; in that case, you could just get a bottle of generic diphenhydramine tablets and use those, but as you said it's linked to dementia and is not good to use frequently (which also isn't stated on any of these sleep aid packages). It just feels like they're trying to subtly hide that fact

personally I've never had 'spider nightmares' from taking Benadryl, either...

My regular brand sells melatonin in pink so idk !!

And unless you bought the 180 count pack of Benadryl, you went back to the store several times in those two months.

Benadryl can come in a bottle. The generic can be bought 35 capsules for $1... what I call bs is 3 = spider nightmares... most are 25mg which means they were only taking 75mg. That's hardly anything. Itll knock you out for newbies, but def won't give the hallucinations the op is talking about.

It does come in a bottle. Had an amoxicillin reaction. That bottle was a lifesaver every four hours of the day, or night. But I also think this is BS. Benadryl will plug you up like nothing else.

Calling bullshit because you don't know things... What's more classic?

Benedryl comes in bottles if you generic. My 50 count bottle of benedryl is $1.25 from dollar tree, 100 count is $3 at Aldi. Plus, Benedryl is often sold as a sleep aid under different brands like Unisom, Diphenhydramine is just colloquially called Benedryl.
