Hallucination

MY miserable Jersey tournament continued today when I lost in 32 moves as White against a local junior.

White to make his 29th move in Spanton (1914) - Jem Gurner (1751)

29.Bd2?
I had sacrificed a pawn in the opening for a long-lasting initiative. My original intent here was to threaten to double on the seventh after 29.Rh7 with what is an unclear position, although Stockfish10 and Komodo9 slightly prefer Black.
Instead I suffered a hallucination that I compounded after …
29...Rd8
… by playing …
30.Bxa5??
There followed:
30...Rxa5 31.Rb8+ Kd7 32.R1b7+ Ke8 0-1
