Hi, my sister was diagnosed with progressive terminal lung cancer back in April 2026, she lives in spain but is coming back to Uk this month, she is currently not having treatment and is showing some worrying symptoms,she is experiencing what I can only describe as extremely vivid dreams where she cant tell reality frm non reality, and also keeps saying she can puddle jump to places ie morph from one place to the other,has anyone else experienced this with a relative?
