Shit.. not a twin BUT..
My brother and I grew up close (18 mo. apart)
We both ended up in the same occupation and same company. (Towing barges in a river, tho we occasionally went outside the river to meet other tugs and pass off barges.
I had a dream one night where a certain boat (The one my brother works on) was in some tumultuous seas. A wave broke over the bow and hit the port forward window.
In my dream I wondered if the window blew out and salty sea water would enter the wheelhouse and damage the electronics. But I never found out in my dream. I woke up.
My brother came home from nightshift and told me a story about them working outside the river. He said a wave must have hit a window because he didn't see until hours later in daylight, but a window was cracked.
I asked, "The port, forward window?" And he confirmed. Then asked how I knew.... I don't know, but my best guess is we all emit a frequency of our energy and those close to us (family) are tuned into our familiar frequency.
But I witnessed it in my dream from a position he was never in.
