Bit of a strange question but just wondered if anyone else has strange hallucinations at night? I have started taking 50mg of amitriptyline and 4 times now I have woke up suddenly seeing a huge spider on my window, convinced it's real I jump up and turn in the light but nothing there. It seems so real at the time and quite distressing. Last night a tarantula crawled under my mirror (supposedly) and I lay terrified. Anyone else experienced this?
