AIBU to think this is Cyber Stalking?

I would keep a diary of these incidents and their impact on you in case they escalate. You have my sympathy, sounds awful.

Looking at a profile isn't cyber stalking.

I admit the watching from windows is a bit odd though!

Oh it does sound very weird, no good putting a higher fence up if he’s watching you from an upstairs window,you have very strange neighbours, you are not being sensitive

This isn't cyber stalking - yet, but it is harrassment and intimidating. Why not keep a diary of his movements and then, perhaps, speak to Citizen's Advice or talk to Age UK. They should be able to advise you what to do.

No not at all, I think it would make me very uneasy. They sound like a right pair of weirdos, somehow creepier because the woman watches you as well, I don’t know what to suggest, but I would keep your distance.

They sound as though they need something to do. Life must be so boring for them.
I'd get a tailors dummy and stick it in the garden----with its bare behind facing them

An elderly gentleman across the road used to watch me and it creeped me out. He died recently and I still find myself feeling uncomfortable working in the front garden.
You are not being over sensitive but I have no idea what you can do.

Sounds weird. Can you afford to have a higher fence or buy a tree that blocks or impedes their view? Have you considered moving?

I don' think you are being over sensitive it all sounds rather weird

No, I don’t think you’re being over sensitive at all, it is very creepy behaviour......
