I can’t say for certain as I’m not qualified, but I definitely think that’s a real experience (but spiritual or something probably?) I wouldn’t define it as “normal” or “not normal” though! I’ve heard of you dream of a deceased loved one and I think interact with them, it’s real. Also, I’ve heard loss of a loved one can bring on a “spiritual awakening” in a person and I wonder if maybe that’s kinda related to your guy’s experience? (again, I don’t not know, just throwing out some information I’ve read about the last few months about related topics) But the fact that you’re BOTH having this dream seems far from coincidental to me…
