Erin McNeil, 23, said the last thing she could remember before waking up in hospital was going to bed in her friend's house.
She told her advocate Dorothy Bain QC that her next memory was seeing a nurse checking on her condition.
She said: "I woke up six weeks later. I remember someone - a nurse - saying to me that I had been in a house fire and did I know who I was and that it was Glasgow Royal Infirmary."
Miss McNeil, of Menstrie, Clackmannanshire, was giving evidence during proceedings at the Court of Session in Edinburgh.
She was rescued by firefighters from her former friend Kerryann Easton's home in Alloa, in the early hours of February 15, 2009.
It has been claimed in proceedings that the accident was Miss Easton's fault and that she failed to keep a good look out while cooking food. This is denied by Miss Easton's legal team.
Miss McNeil claims she suffered serious burns to her upper and local body and vocal cords and lung injury because of smoke inhalation and post traumatic stress disorder. She claims this has left her unable to pursue a singing career and is seeking compensation for the incident.
Lawyers acting on behalf of Miss Easton, of Tullibody, Clacks, maintain that Miss McNeil is fit for work.
The hearing before Lord Bannatyne continues.
