Cover art for Heirloom lyrics by Björk

I would imagine this is about a certain time when both her Son and Mother helped her by her bed when she was ill and administered warm mix of medicine of some type for her.

She would remember this moment of close unity, especially when she feels unwell or looses her voice from sickness or strain. It may distress her.

And this has a remembrance factor for her to feel better - her closest loved ones helping her become well again. (Recurring dream)

Lyrically exciting :)

My Interpretation

I think this song is about DMT, a very powerful and naturally occurring psychedelic drug found in many plants and in the human body. Lets do a 'line by line' analysis:

'I have a recurrent dream' Deja vu and seeing the same 'little beings' is very often associated with the hallucinations brought on by DMT.

'Everytime I lose my voice' DMT is commonly smoked. The smoke is incredibly harsh and quite painful to inhale. It is not uncommon to lose one's voice or become hoarse for up to 24 hours after inhalation of the smoke.

'I swallow little glowing lights' DMT effects...

Not Valid
